Lab Alumni


RachaelRachael Workman earned her Bachelors in Biology from West Virginia State University, Masters from Portland State in Oregon, and worked as a summer research assistant at Cornell and Oregon State Universities. After graduate school she farmed for a season in Maine, and is excited to be back in the lab as the tech for the Timp Lab. In her spare time she cares lovingly for her many plants, collects more books than she could ever hope to read in her lifetime and plays her euphonium (it’s like a small tuba, don’t feel bad, no one else has heard of it either).



PhD Students:

isac_leeIsac Lee is a third year PhD student in Biomedical Engineering. He completed his undergraduate studies at the University of Texas at Austin in Biomedical Engineering. His current research project is based on determining the spatial organization of DNA via sequencing, using a technique called Hi-C. He has a very cute nephew (not a son) who is 2 years old as of March 2016!




Yunfan2Yunfan Fan is a first year graduate student majoring in Biomedical Engineering. She enjoys literature, art, and following the parade of sadness that is Cleveland sports. Her work is primarily involved in leveraging long-read nanopore sequencing in infectious disease and metagenomic settings. She also fondly hopes that one day, the people of Earth will love her as their benevolent overlord as she rules them from her palace in space.




timTimothy ‘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




B Avin Bio Brittany Avin is a second 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.


headshot 2Jawara Allen is a second 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.


Masters’ Students:

shaoStephanie Hao is a second year Master’s student in Biomedical Engineering. Her work mainly involves infectious disease sequencing on the Illumina MiSeq and Oxford Nanopore MinION. She enjoys reading and experimenting with foods, and on rare occasions can be caught humming tunes from random musicals.







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.
