BIOLOGICAL SCIENCES NEWSLETTER

NOTES FROM THE CHAIR

 

Dr. Dale Noel Last year in the fall and spring newsletters, we reported the retirements of four stalwart professors in the department. We now can say that all four of these vacant positions have been filled, three new faculty being hired since our last newsletter in the fall.  They are professor Stefan Schnitzer, a community ecologist, assistant professor Edwin Antony, a biophysical enzymologist, and assistant professor Tony Gamble, an evolutionary developmental biologist. Each will be working at Marquette during at least part of the summer and officially assumes his position at the end of August. The fourth position was taken by assistant professor Anita Manogaran starting this past fall. She is a molecular cell biologist studying prions in yeast. Look for profiles of their work in upcoming newsletters. In other respects the past two years have been a period of changes and intense planning for even greater changes that will reach fruition in the next two or more years. Almost everything we do is undergoing modifications --curricula, the way we deliver the curricula, procedures within the department, research activities and development of research plans. A last change to add is that I am stepping down as chair at the first of July, to be succeeded by Dr. Ed Blumenthal. I see a very bright future for this department.

In Memorium

 

Submitted by Dr. Brian Unsworth, Professor Emeritus and Department Chair 1998-2004

On Christmas Eve 2014, Sandra Priegel-Hughes died unexpectedly. She worked tirelessly and conscientiously, serving four departmental chairmen. “......May you continue to inspire us: To enter each day with a generous heart, to serve the call of courage and love until we see your beautiful face again in that land where there is no more separation, Where all tears will be wiped from our minds and where we will never lose you again.” Excerpted from On the Death of the Beloved by John O’Donohue.

Smith Lecture

The 28th annual Oliver Smith Memorial Lecture was held on April 10th. This year’s lecture discussed “Biodegradation of Oil, from the Exxon Valdez to the Deepwater Horizon”, and was presented by Dr. Lily Young, Distinguished Professor of Environmental Microbiology as well as Provost at Rutgers, The State University of New Jersey.

 

Dr. Young is internationally recognized for her scientific contributions to the role of anaerobic microorganisms that degrade a host of harmful organic chemicals like pesticides and petroleum components. The research in her laboratory targets novel anaerobes and the chemistry of the degradation pathways that they carry out. In 1994, her publication on degradation of toluene and m-xylene and transformation of o-xylene by denitrifying enrichment cultures was noted as one of the 10 most highly cited papers in the field of Ecology and Environmental Sciences. Her research has shown that petroleum hydrocarbon compounds including benzene, toluene, xylenes, naphthalene, phenanthrene, and hexadecane, are no longer considered recalcitrant under anaerobic conditions. They have proven that anaerobes have novel mechanisms to activating these molecules. For toluene the bssA gene codes for benzyl-succinate synthase Lily Young | Oliver H. Smithand they have shown that different anaerobes have analogues of bssA to degrade naphthalene and hexadecane. They have also demonstrated that some anaerobes have a different and unique mechanism for hexadecane degradation involving glycyl radical chemistry. These anaerobic mechanisms have been underexplored in anoxic habitats and for remediation of these contaminants. More recent research has also targeted the activity of environmental microbes on the reduction and oxidation (and cycling) of arsenic found in groundwater both locally and worldwide, processes that affect environmental toxicity.

 

Dr. Young has published over 100 scientific papers. She has been elected as a Fellow of the American Academy of Microbiology and the American Association for the Advancement of Science. She has received separate Research Excellence Awards from Cook College, New Jersey Agricultural Experiment Station and the Board of Trustees of Rutgers University. Dr. Young has also received the Proctor & Gamble Award in Applied and Environmental Microbiology from the American Society for Microbiology. She has served on the editorial boards of the journals Applied and Environmental Microbiology, Microbial Ecology, and Biodegradation. Dr. Young has also served as Chair of Division Q, Environmental and General Applied Microbiology of the American Society of Microbiology.

 

 

STEM-MBA program

Marquette has unveiled a new BS/MBA program starting Fall 2015. This program allows students to earn an undergraduate degree in one of several STEM fields (Biological Sciences, Biochemistry & Molecular Biology, Physiological Sciences, Athletic Training Biomedical Sciences, Chemistry, Computer Science, Exercise Physiology, Math, or Physics), and an MBA in just five years. In the STEM-MBA program, students take business foundation courses as part of their undergraduate curriculum and then begin graduate-level coursework during their senior year.

 

Alumni Mentor Program

 

The Alumni Mentor Program is designed to match a Marquette Alumni with a current student in order to provide excellent networking, resume building, and shadowing opportunities, as well as to broaden students' understanding of life after Marquette.   The matchmaking process attempts to pair a student with an Alumni that had the same major (or at least was in the same college) as the student, or has a career that the student is interested in pursuing.  After some kickoff events, mentors and mentees will usually communicate through email, texts, phone calls, and sometimes even Skype to discuss times when they would like to meet, shadow, etc.  Throughout the year, mentors and mentees are invited to group events hosted by the Alumni Mentor Program.  Between these events, students have the opportunity to shadow their mentors or communicate with them to discuss their career path/goals/future direction (if the mentors live out of state and are unable to be shadowed).  

 

Alek Druck (Junior Physiological Sciences major) came into the program not knowing what to expect; he had been involved in other "job shadowing" programs in the past, but didn't know how much different the Alumni Mentor Program would be.  Looking back, he feels this program went above and beyond his expectations of a typical networking or shadowing program.  This is because the underlying connection between the Alumni and the student is Marquette, thus can see how each mentor embodies that idea of "men and women for others".  Mentors truly want to help undergraduates be successful, and through their kindness and desire to help, true friendships are made. Alek was able shadow his mentor, Dr. Robert Panther, multiple times throughout the year, giving him memorable experiences in the hospital setting. Alek was also invited to have dinner at Dr. Panther’s home, and they conversed over lunch and dinner in the city many times when he was in Milwaukee.  The combination of these experiences created a lasting bond between Alek and his mentor. Dr. Panther demonstrated the kindness and generosity that doctors can possess, and has become a role model for Alek of what a good doctor truly resembles.  Alek highly recommends current students to apply for this program, and hopes more and more Marquette Alumni continue to apply to be mentors so the program can expand.

 

 

HRISTOVA AWARDED MMSD GRANT

Dr. Hristova

A major group of persistent organic pollutants, polycyclic aromatic hydrocarbons (PAHs) are widely found in natural environments. PAHs presence has been previously detected in sediments of the Southern Basin of Lake Michigan, including the Outer Milwaukee Harbor. Characterization of microbial biodegradation potential in sediments is a key issue in determining the fate of these persistent contaminants in fresh water coastal environments.

 

Dr. Krassi Hristova received a funding from MMSD to determine if the Lake Michigan coastal microbial communities have the potential to biodegrade a mixture of PAHs. Understanding microbial diversity and which microorganisms are involved in biodegradation of these pollutants will help in a targeted approach to isolate these environmental organisms and in the design of bioremediation approaches. In addition, Dr. Hristova’s lab will attempt to determine if detected concentrations of PAHs pose risk to benthic aquatic organisms and thus threaten environmental health.

Petrella awarded Way Klingler Young Scholar Award

Dr. Petrella Young Scholar Award

Temperature has special environmental interest because, despite perhaps being in the range of only a few degrees, the temperature increases due to global warming have significant and direct consequences on how animals develop. In addition, there are many connections of Dr. Lisa Petrella’s work to human biology, including loss of male fertility at high temperature,”

-Dr. Dale Noel commenting on Dr. Petrella’s research.

Dr. Lisa Petrella, who is studying the effects of changing temperatures on germ cells, has been awarded a Way Klingler Young Scholar Award, which supports promising young scholars in critical stages of their careers. The award up to $32,000 is intended to fund $2,000 in operating costs and to cover up to 50 percent of salary to afford the recipient a one-semester sabbatical. Dr. Petrella says, “Understanding what goes wrong in these cells has implications not only in human and livestock fertility, but also in potentially catastrophic loss of certain types of invertebrate populations with an increase in global temperatures.

After coming back from Winter break the Biological Undergraduate Society (BUS) hit the ground running as it hosted a mini-talk night two weeks into the new semester to provide students with different options of what you can do with a Biology degree outside of professional and graduate school. In March, a Lab Explorations event gave students a glimpse into the different types of research that faculty in the department conduct. Students toured professors’ labs and had the opportunity to learn about their work in small groups.

In April, BUS students were invited to Byron Kilbourn Elementary School to volunteer at their First Annual Science Family Fun Night. The students planned and demonstrated experiments for Kilbourn students and their families. The parents and students at Kilbourn School were inspired by exploring science. Many of them had never had the opportunity before to explore science as such a positive experience.

Awards

 

Catherine Welsh Smith Research Award

Aman GrewalThe Catherine Welsh Smith Award in Biological Sciences recognizes outstanding achievement in biological research by a junior or senior majoring in Biological Sciences. The award committee selects the winner from nominations from faculty of students who have displayed talent for research, including initiative, independence, and the ability to design and carry out experiments.


Aman Grewal, this year’s winner, has spent the past two years working in Dr. Edward Blumenthal’s lab. His research was focused determining the function of the Drosophila drop-dead (drd) gene in the eggshell. He was trying to determine why the vitelline membrane of drd mutants does not properly crosslink. He performed many assays where he incubated mutant oocytes in particular solutions as an attempt to rescue crosslinking. However, these attempts were not successful and the lab now has a new hypothesis explaining why the vitelline membrane proteins do not crosslink. After graduation in May, Aman will be attending the University of Wisconsin-Madison School of Veterinary Medicine to fulfill his childhood dream of becoming a veterinarian.

Biochemistry/Molecular Biology Research Award

Kylli PaavolaThe Department of Biological Sciences Research Award in Biochemistry and Molecular Biology recognizes outstanding achievement in research by a junior or senior majoring in the Biological Sciences Department. The award committee selects the winner from nominations from faculty of students who have displayed talent for research, including initiative, independence, and the ability to design and carry out experiments on their own, and from an abstract submitted by the student.


BMB Research Award winner Kylli Paavola is a graduating senior double majoring in Biochemistry & Molecular Biology and Political Science. She started working in Dr. Krassimira Hristova’s environmental microbiology lab in June 2014, and continued her research throughout the 2014-2015 academic year. The overall objective of her research is to determine if invasive dresseneid mussels, native if the Milwaukee Harbor, could be indicators for water pollution with human pathogens. Utilizing quantitative real time PCR she monitored water, sediment and mussels samples for human fecal biomarkers following an environmental Combined Sewage Overflow event in Lake Michigan. In addition, mussels and water were monitored from an in vitro lab experiment set up to mirror the environmental event, where mussels were fed with raw sewage from Jones Island Waste Water Treatment Plant. After graduation, Kylli will be attending the University of Wisconsin- Milwaukee for her Master’s in Public Health, emphasis in Environmental Science/Epidemiology.


Physiological Sciences Research Award

Monica LopezThe Department of Biological Sciences Research Award in Physiological Sciences recognizes outstanding achievement in research by a junior or senior majoring in the Biological Sciences Department. The award committee selects the winner from nominations from faculty of students who have displayed talent for research, including initiative, independence, and the ability to design and carry out experiments on their own, and from an abstract submitted by the student.


Monica B. Lopez Suarez, winner of this year’s Physiological Sciences Research Award, has spent the past two years working in Dr. Robert Fitts’ lab doing cardiac electrophysiology research. Her project focused on the effects acute running has in protecting against ischemia induced heart cell death with the use of rat hearts as a model system. This research has clinical relevance, as cardiovascular disease is the leading cause of death worldwide. Also part of her whole heart work, she has spent time studying the effects exercise training has on the monophasic action potential (MAP) while exposed to conditions of regional ischemia and high heart rates. This tests the hypothesis that exercise training results in a shortened monophasic action potential during ischemia and at high heart rates due to increased KATP channel function. After graduating in May with a Physiological Sciences degree, Monica will be working full-time in the Medical College of Wisconsin – Tissue Bank as a Laboratory Assistant.


Biological Sciences Academic Achievement Award

Jamie CollinsThe Biological Sciences Academic Achievement Award recognizes the outstanding academic achievement in the Biological Sciences Department by a senior majoring in Biological Sciences, Physiological Sciences, or Biochemistry/Molecular Biology. The award committee selects the winner based on a cumulative GPA of 3.50 and above, the student’s sciences GPA, and a letter of recommendation from a faculty member.


Academic Achievement Award Winner, Jamie Collins is a senior majoring in Biological Sciences and Spanish, and minoring in English. She is also in the Honors Program. Jamie has spent the past year researching in Dr. Allison Abbott's lab, where she has studied calcium-dependent rhythmic behaviors. Specifically, she has worked on investigating the functions of two genes, dec-1 and dec-2, in regulation of C. elegans defecation. After graduation, Jamie will attend medical school at the Medical College of Wisconsin.

AWARDS

Schmitt Fellowship

Arthur J. Schmitt was an industrial executive who expressed his commitment to education, and the development of responsible leadership through Christian principles and ideals. He founded the Arthur J. Schmitt Foundation in 1941, dedicating its resources toward fashioning a better and more humane world. The Arthur J. Schmitt Leadership Fellowships are awarded to eight-ten MU students in doctoral programs each year. Josh Garlich was awarded this prestigious fellowship for the 2015-16 academic year.


Oliver Smith Achievement Award

Alexis OnderakThis annual award is sponsored by the Oliver H. Smith Memorial Fund to recognize exceptional achievement by a graduate student in the Ph.D. program of the Department of Biological Sciences. This award is based on grade point average (GPA), research activity and scholarly achievements.


After graduating with a Bachelor’s of Science degree in 2012, this year’s recipient, Alexis Onderak continued her studies at Marquette, where she currently holds a 4.0 cumulative GPA in the biological sciences graduate program. Initiating a novel research project on the role of RNA surveillance on mammalian cell health, Alexis’s research seeks to understand how impaired RNA processing and degradation affects cell proliferation and differentiation. To explore this, she has focused her studies on the RNA helicase Skiv2l2, an essential component of nuclear non-coding RNA processing and degradation, that is dysregulated in cancer and amyotrophic lateral sclerosis (ALS). She has found that loss of Skiv2l2, either through transcriptional pathways or RNAi, results in increased cell differentiation and cell cycle arrest, suggesting that proper RNA processing and degradation is necessary to maintain cells in a proliferative state. Alexis received a travel fellowship to present this research at the Rustbelt RNA Meeting in Pittsburgh, Pennsylvania and has also given a poster presentation at the RNA Society Meeting in Madison, Wisconsin. In addition to her academic pursuits, Alexis has enjoyed acting as a teaching assistant for introductory biology courses and volunteering within the Marquette community. She hopes to start a career as a forensic scientist upon graduation.

Scholl Award

Zac LunakSponsored by the Dr. Scholl Foundation, this award goes to a graduate student who has performed outstanding research as demonstrated by the submission/publication of a first author manuscript in a peer-reviewed journal.


Zac Lunak won this year’s Scholl Award for his paper, “A quinol oxidase, encoded by cyoABCD, is utilized to adapt to lower O2 concentrations in Rhizobium etliRhizobium etli, like many bacteria, aerobically respires through a variety of terminal oxidases. The quinol oxidase, encoded by cyoABCD, is of particular interest because its role in the cell is not understood in organisms that already contain cytochrome c oxidases. In his paper, Zac and his mentor, Dr. Dale Noel, demonstrated that this quinol oxidase (Cyo) was important for efficient adaptation to lower oxygen concentrations by analyzing the ability of a cyo mutant to grow in various oxygen concentrations. Furthermore, the transcription of cyo is increased when cells are subjected to lower oxygen concentrations. This work has led to a better understanding of how bacteria adapt to their surrounding environment, and specifically how they adapt to fluctuating oxygen concentrations, a key attribute to many soil bacteria.

Dr. Catherine Grotelueschen Scholarship

An annual scholarship from the Dr. Catherine Grotelueschen Scholarship Fund for Biology is awarded to provide financial assistance toward the summer research of a graduate student.


Yi Liu won this year’s Grotelueschen Scholarship for summer research. In vivo, the microtubule (MT) system is crucial for almost all different cellular events. Generally speaking, the MT system is composed of MTs and various microtubule-associated proteins (MAPs). Binding of distinct MAPs to the MTs will have significant impacts on either the assembly or disassembly rate of MTs. Therefore, the interplay of MTs and MAPs mostly decides the fates of MTs among growing, pausing and shrinking. Studies have demonstrated that cells can actively change the MT-MAPs interplay when necessary, however little is known about how external stimuli can affect the interplay. Chlamydomonas is one type of unicellular green algae that is sensitive to numerous environmental stimuli. Using a transgenic strain expressing an essential MAP (EB1) tagged with a fluorescence protein (FP)—-EB1-FP, Yi was able to monitor the dynamics of EB1-FP decorated MTs under different extracellular stimuli, and found out that physical compression, illumination, and pH shockall can drastically alter the MT-EB1 interplay. Interestingly, cells in different metabolic states show distinct sensitivity to the stimuli. Over the summer, supported by the Dr. Catherine Grotelueschen Scholarship, Yi will focus on quantification of the difference of EB1-FP dynamics under various metabolic states.
