Katherine Maniates
Katie ManiatesResearch Interest:
microRNAs are ~22 nucleotide non-coding RNAs that function to regulate genes post-transcriptionally. While it is known that microRNAs are necessary for proper development and physiology, the functions of individual microRNAs are largely unknown. My research focuses on understanding how the miR-44 family of microRNAs regulates sperm formation and function in C. elegans. I have identified important roles for the miR-44 family in the regulation of spermiogenesis and the sperm oocyte switch. I am currently identifying the specific genes and pathways that are targeted by the miR-44 family.

Lu Lu
Lu Lu Research Interest:
miRNAs are short non-coding RNAs with a length of -22 nucleotides that regulate gene expression at post-transcriptional level.  miRNAs have been shown to regulate crucial development and physiological processes. And dysregulation miRNA expression is associated with a wide array of human diseases, including male factor infertility. While studies have suggested that miRNAs play important regulatory roles for producing functional sperm, the specific roles are not well understood. My research aims to address the specific roles of individual miRNA in sperm production and sperm function using C. elegans as model.

Elliot CorlessResearch Interest: 
Photosynthetic bacteria growing in the dark require the hetero-octameric complex dark operative protochlorophyllide oxidoreductase complex (DPOR) to reduce the chlorophyll precursor protochlorophyllide (PChlide) to chlorophyllide (Chlide.) DPOR consists of 3 parts (Bch-L, Bch-N, and Bch-B) which catalyze a specific double bond reduction requiring 4 ATP, multiple binding and dissociation events, as well as inter- and intra-complex communication. My research focuses on communication between halves of the complex, pre-steady state kinetics, and structure determinations.

Nilisha Pokhrel
Nilisha PokhrelResearch Interest: 
Replication Protein A (RPA) is an abundant single- stranded DNA (ssDNA) binding protein in eukaryotes. It binds to ssDNA with high affinity, prevents formation of secondary DNA structures and protects it from nucleases. Individual subunits of RPA bind to ssDNA through their four DNA binding domains (DBDs) i.e DBD-A, DBD-B, DBD-C and DBD-D. Despite the versatile roles of RPA in maintenance of the integrity of DNA, its precise mechanism of action remains unclear. I am interested in answering two fundamental questions regarding RPA:
1. What is the precise mechanism underlying engagement of individual DBDs of RPA on ssDNA?
2. How does RPA ‘hand- over’ ssDNA to other DNA binding enzymes which have comparatively lower binding for ssDNA?
To answer these questions, I have generated fluorescent RPA with fluorophores incorporated at specific DBDs, which allow us to monitor dynamics of that particular DBD in a multi-protein reaction.

Sahiti Kuppa
Sahiti KuppaResearch Interest:
DNA is damaged during normal replication and by external carcinogens or radiation. Ultraviolet light generates bulky DNA adducts that are repaired by the Nucleotide Excision Repair (NER) system. Defects in NER enzymes lead to genomic instability and result in major diseases such as skin cancer (Xeroderma pigmentosum (XP), Trichothiodystrophy (TTD) or Cockayne Syndrome (CS) etc.). Replication protein A (RPA) and Xeroderma Pigmentosum group A (XPA) are two proteins that are known to play a significant role during NER. My research focuses on understanding how RPA and XPA bind to damaged versus undamaged DNA and how they influence each other during the assembly of the NER bubble – a key intermediate for successful repair of bulky lesions.

Identifying diverse mechanisms of speciation without invoking overly-simplistic models of allopatry and genetic drift is a cornerstone investigation of 21st century evolutionary biology. My work focuses on disentangling the genomic mechanisms of speciation. Namely, I am working to understand how independently evolving genomes combine during the process of interspecific hybridization and the role of regions in the genome that may be more susceptible to large changes over short periods of time, such as the sex chromosomes or regions under strong selection. We have established a model system to investigate the role of sex chromosomes on speciation in a group of speciose gecko lizards endemic to the Puerto Rican Bank.

Rachelle Beattie
Rachelle BeattieResearch Interest: 
Misuse of antibiotic compounds in healthcare, veterinary medicine, and agriculture has led to an increase in bacterial antibiotic resistance in both the clinic and the environment. Of these, environmental antibiotic resistance has recently become an important area of research as antibiotic resistance bacteria (ARB) and antibiotic resistant genes (ARGs) are now recognized as emerging biological contaminants. ARB and ARGs in the environment are prevalent in areas of concentrated agriculture due to the use of antibiotics for disease treatment and prevention. My research aims to identify how common agricultural practices (such as manure fertilization of farmland) impact the abundance and distribution of antibiotic resistance genes and bacteria in an area of concentrated livestock farming: Kewaunee County, Wisconsin. Additionally, we are working to elucidate connections between environmental and clinical antibiotic resistant pathogens in northeastern Wisconsin.

Sexual reproduction affords many benefits to multicellular organisms, but it has a deeply conserved flaw: fertility is temperature sensitive. I am interested in determining the effects temperature stress has on fertility. Currently, I am examining the temperature sensitive processes in sperm production, migration, and fertilization in Caenorhabditis elegans males. In addition, I am exploring the natural variation in temperature stress response by examining these effects in both the standard laboratory wild type, N2, and wild isolates collected from across the globe. I hope to assemble a comprehensive portrait of the effects temperature stress has on these crucial processes at a cellular and molecular level.

I am working on cold tolerant rice root microbiome and I am trying to find differences between cold tolerant and non-cold tolerant rice root microbiome. In the proposed research we aim to identify positive root-microbiome interactions that promote cold tolerance in rice. To our knowledge, the root microbiome in rice has not been thoroughly studied and the effect of the microbiome on rice cold tolerance is completely unknown. The results of these experiments offer a basic understanding of microbiome-plant relationships during temperature stress, potentially unlocking improved rice growth in cold environments. This could potentially expand the agricultural range of the world’s most important staple crop.

Research in Dr. Rosemary Stuart's lab focuses on mitochondrial biogenesis and function. Dr. Stuart is NOT accepting new Ph.D. students into the lab. 

Vera Strogolova
Vera StrogolovaResearch Interest: I am interested in molecular mechanisms regulating cellular metabolism. My current work focuses on the regulation of mitochondrial respiration and how this reflects the metabolic needs of the cell.

 Research in Dr. Pinfen Yang's lab focuses on the control of flagellar motility. Dr. Yang is accepting new Ph.D. students into the lab. 

Brandon M. Wills
Brandon WillsResearch Interest: The Yang lab uses the green alga Chlamydomonas reinhardtii to illuminate biology. Both flagella and cilia play central roles in most human cells. One major question is how various components are delivered to the flagellar compartment. However, the autofluorescence in the cell body of Chlamydomonas hinders imaging of the trafficking process. I am developing strategies to overcome the autofluorescence so that we can further investigate this process.
