Winston Timp

Winston Timp is an assistant professor in Biomedical Engineering at Johns Hopkins University. He earned bachelor degrees in Biochemistry, Chemistry, Physics and Electrical Engineering from the University of Illinois at Urbana. He then earned his masters and PhD in Electrical Engineering from MIT, working at the Whitehead Institute in Paul Matsudaira’s lab, focusing his thesis work on the study of cellular communication in a 3D microenvironment. After receiving his doctorate, he trained as a postdoc at Johns Hopkins in the labs of Andrew Feinberg and Andre Levchenko, studying the epigenetics of cancer.

Norah Sadowski

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.


Paul Hook

Paul Hook is a postdoctoral fellow in Department of Biomedical Engineering. He earned his bachelor’s degree in Biochemistry and Molecular Biology at the Pennsylvania State University. He earned his PhD in Human Genetics in Andrew McCallion’s lab at the Johns Hopkins University School of Medicine where his thesis work focused on pinpointing the genes and variants underlying genome-wide association signals by using genomic data from disease-relevant cell populations. Outside of science, Paul enjoys exploring Baltimore, getting way too into college football, cooking, and playing disc golf.

PhD Students:

Yunfan Fan

Yunfan Fan is a fifth 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.

Roham Razaghi

Roham Razaghi is a four 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

Ariel Gershman is a third 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

Brittany Pielstick is a third 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

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.

Sheridan Cavalier

Sheridan Cavalier is a third 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.


Quinn Hauck

Quinn Hauck is an undergraduate majoring in biomedical engineering from Seattle, WA. He is fascinated by the complexity of genetic information and cellular pathways, and hopes to understand it better through his work. In his free time, he enjoys hiking around Washington state and plays on the men’s ultimate frisbee team at Hopkins
