Norah Sadowski earned her Bachelors degree in biotechnology from the University of Nebraska at Omaha.  Her previous research includes enzyme characterization and optimization of in vitro toxicology assays. She is ecstatic to return to an academic lab from industry and is focused on the current DNA and RNA modification research in the Timp Lab in her role as a research technologist. When not in the lab, she is probably backpacking, rereading Sherlock Holmes, binge watching Star Trek, or working on one of her too many ongoing projects.


PhD Students:

Isac Lee is a fifth year PhD student in Biomedical Engineering. He completed his undergraduate studies at the University of Texas at Austin. He spends most of his days in lab looking at slickdeals and amazon. He is also interested in the relationship between the epigenome and the genome and developing techniques to better observe that relationship, especially in the context of cancer progression.

Yunfan Fan is a fourth year PhD student in Biomedical Engineering. Her work primarily involves leveraging sequencing data in infectious disease and metagenomic settings, both for diagnostic purposes and for understanding pathogenic mechanisms on a molecular level. She fondly hopes that one day, the people of Earth will love her as their benevolent overlord while she rules them from her palace in space.


Timothy ‘Gilfunk’ Gilpatrick is a grumpy old grouch man who lives in a cave where he feeds on lawn refuse. Every now and then he comes out to do experiments. His research interests include epigenetic regulation of transcription and mechanisms of epigenetic inheritance.
He aims to leverage sequencing technologies to better understand how cellular diversity, development, and the response to stimuli are reflected in the transcriptome and epigenome


Roham Razaghi is a second year PhD student in the department of Biomedical Engineering. He earned his undergraduate degree in Bioengineering from University of California, San Diego (UCSD). His current project involves developing novel technologies for sequencing/discriminating of proteins. He is also interested in working on autoimmune disorders, specifically Type 1 Diabetes. If not in lab, you can certainly find him on the soccer field.


Ariel Gershman is a first year PhD student in Biochemistry Cell and Molecular Biology (BCMB). She completed her Bachelors in Pharmacology at the University of California, Santa Barbara. She is currently interested in understanding epigenetic regulation of repetitive regions of the genome and developing pipelines to further decipher the role of repetitive sequences in genome function. When not in lab she enjoys playing soccer, hiking and binge watching medical dramas on Netflix.


Brittany Pielstick is a first year PhD student in Biochemistry Cell and Molecular Biology (BCMB). She earned her bachelor’s degree from Brigham Young University in microbiology. Her current research interests include studying genetics and epigenetics in relation to metabolism and cancer. When not in lab she enjoys long distance running and trying out new dinner recipes.


Brittany Avin is a fourth year PhD student in the Biochemistry, Cellular, and Molecular Biology (BCMB) Program at the School of Medicine. She completed a double major in Biochemistry and Genetics at Clemson University. Brittany is mentored by Dr. Umbricht and Dr. Zeiger in the Department of Surgery, and she is investigating the role of DNA methylation in the promoter region of human telomerase reverse transcriptase (hTERT) in alternative splicing in thyroid cancer. In her spare time she enjoys cancer advocacy, playing basketball, and sailing.


Jawara Allen is a fourth year PhD student in Biochemistry Cellular and Molecular Biology. He completed his undergraduate studies at Duke University with a major in biology and a minor in evolutionary anthropology. His current research project focuses on discovering how Bacteroides Fragilis toxin (BFT) alters the epigenome in colon epithelial cells., working primarily in Cindy Sears’s lab.


Sheridan Cavalier is a first year PhD student in the Biochemistry, Cellular, and Molecular Biology (BCMB) Program at the School of Medicine. She’s interested in activity-induced alternative splicing in neurons, working primarily in Rick Huganir’s lab. She is a dynamic figure, often seen scaling walls and crushing ice. She has been known to remodel train stations on her lunch breaks, making them more efficient in the area of heat retention. On weekends, to let off steam, she participates in full-contact origami. Years ago she discovered the meaning of life but forgot to write it down.


Undergraduates:

Tatiana Gelaf Romer is a biomedical engineering undergraduate from Dover, Massachusetts. Through her research, she’s hoping to get a better understanding of how we can study and manipulate genomes. In her free time, she likes to read, take hikes, build jigsaw puzzles, and cuddle dogs.


Nick Garza is an undergraduate from San Antonio, TX majoring in Biomedical Engineering and Computer Science. Since starting college he’s had an interests in the technology and software behind DNA sequencing and how it can be used to link genetics with disease. In his free time, he enjoys eating at his way through Baltimore, playing violin, and wrangling his three dachshunds at home.
