Daniel Berenzy
Daniel Berenzy
Research Asssitant I
daniel.berenzy (at) jax.org

Daniel graduated from Florida Gulf Coast University (FGCU) with a degree in Biotechnology, while working with Dr. Takashi Ueda in the school’s Biotechnology lab. Upon graduating from FGCU, Daniel immediately joined the Tewhey Lab as a Research Assistant and concurrently enrolled in the Professional Science Masters (PSM) program in Bioinformatics at the University of Maine. As a Research Assistant in the Tewhey Lab, Daniel contributes to several different projects in both the “wet” and “dry” lab but his expertise is in Biotechnology methods. In his free time, Daniel studies for a Master’s degree but is also an avid Cyclist, Climber, Kayaker and all-around outdoorsy type.


John Butts
John Butts
Graduate Student
john.butts (at) jax.org

John graduated from University of Dayton with a B.S./M.S. in Biology. It was there he first began his interest in gene regulation, particularly cis-regulatory elements, while working with Dr. Thomas Williams studying the evolution of pigmenation patterns in Drosophila. Following graduation John joined Dr. Victoria Meller’s lab at Wayne State University working as Lab Manager and Research Assistant studying the impact of chromatin conformation on dosage compensation in fruit flies. As a PhD student John hopes to continue to probe the logic underyling CREs and how advancements in experimental methods can enahance this study. In his free time John enjoys making music, running, and playing tennis.

irodcast

Rodrigo graduated from Georgia State University with a doctoral degree in mathematics, focusing in deep learning research. As a postdoctoral associate in the Tewhey lab, Rodrigo works on generative deep-learning models for cis-regulatory elements and deriving new synthetic elements for desired regulatory functions. In his spare time, Rodrigo enjoys practicing music, biking, and learning about new AI advances.

deweyhannah

Hannah graduated from the University of Maine with a degree in Mathematics, while working with Dr. Andre Khalil in the CompuMAINE lab. Before joining the Tewhey Lab, Hannah completed postgraduate degrees in Applied Mathematics (2015) and Bioinformatics and Computational Genomics (2019) at Rensselaer Polytechinic Institute and Queens University Belfast respectively, as well as serving as a Peace Corps Volunteer in Namibia. Now, as a data analyst in the Tewhey Lab, Hannah works developing pipelines to be used in the analysis of MPRA count data as well as participating in the analysis itself. In her free time Hannah enjoys baking, sharing said baked goods with other lab members, and knitting.


Natalia Fuentes
Natalia Fuentes
Undergraduate Student
nfuentes (at) college.harvard.edu

Natalia is a rising junior at Harvard College, studying Integrative Biology with a secondary in Ethnicity, Migration, and Rights. She joined the Tewhey Lab as a member of the 2019 JAX Summer Student Program, and completed a project using a Massively Parallel Reporter Assay (MPRA) to test the regulatory function of machine-learning derived synthetic elements. As a returning undergraduate student, she’s working to computationally characterize this library of novel sequences using known biological markers. With her spare time, Natalia enjoys performing with Mariachi Véritas, getting lost on mountains in Maine, and taking her indoor cat outside.


Susan Kales
Susan Kales
Research Assistant III
susan.kales (at) jax.org

Susan graduated from the University of Colorado, Boulder with a degree in Molecular Cellular Developmental Biology. Before joining JAX for four years Susan worked at Merck & Co. as a Research Biologist. Susan worked for six years in Tom Jessell’s lab and during that time held a dual position for four years in the Jessell and Axel labs at Columbia University. Susan was there when Dr. Axel won the Nobel Prize. Prior to working at Columbia University, Susan worked at MSKCC in Manhattan in a molecular diagnostic lab and she worked at Chugai Pharmaceutical Co. in Tokyo, Japan in the International Group. Susan is a Research Assistant in the Tewhey Lab and contributes to many different projects but her expertise is ES and iPS cell work. In her spare time Susan likes to paint, draw, walk/hike with her dog and husband, cook and be on the water boating or swimming.

@kousuke_mouri

Kousuke graduated from Kyoto University with a degree in life science, while working with Dr. Tadashi Uemura by using six-legged fruit fly. Before coming to Jax, Kousuke had been working with four-legged mouse as a postdoctoral fellow with Dr. Toshihiko Shiroishi at National Institute of Genetics, Japan. Now, as a postodoctoral associate in the Tewhey lab, Kousuke works 2-legged human genetics to decipher the mechanisms of the cis regulatory element which makes wonderful variety of animal morphology and phenotype. In his free time Kousuke enjoys snowboarding and taking care of his kawaii tortoise, Chicago.


Luke Parsley
Luke Parsley
Graduate Student
luke.parsley (at) jax.org

Luke graduated from Rollins College with a degree in Biochemistry/Molecular Biology. During undergraduate, he conducted research in both the laboratories of Dr. Jurrien Dean studying germ granule trafficking in developing oocytes, and Dr. Kasandra Riley profiling ncRNA expression of S. epidermis in stress response. As a graduate student in the Tewhey lab, he employs Massively Parallel Reporter Assays (MPRA) to create enhancer profiles for disease-associated loci. In his free time, he is an avid runner that enjoys Star Trek, hiking, and Chinese food.

@Ry_2E
rtewhey

Ryan is a human geneticist with expertise in developing large-scale screening methods to understand how genetic variation impacts human traits and disease. His primary focus is the investigation of non-coding regions of the genome that control gene expression. He has pioneered the use of massively parallel reporter assays (MPRA) and CRISPR based screens of non-coding regions to identify causal alleles from genome wide association studies. His broad interests lie in the application of novel technologies to answer questions related to human health and disease. His time is evenly divided between experimental and computational approaches. Ryan completed his undergraduate degree from the University of Maine, Orono. He received his PhD from the University of California, San Diego in 2012 while carrying out work at The Scripps Research Translational Institute. He completed is postdoctoral work at Harvard University and The Broad Institute. His awards include Forbes Magazine’s 30 under 30, NSF/A-STAR EAPSI fellow, the Charles J. Epstein Award for Research Excellence by the American Society of Human Genetics, and an NHGRI Pathway to Independence Award. Ryan is currently an assistant professor at The Jackson Laboratory in Bar Harbor and holds appointments at Tufts University School of Medicine and The University of Maine Graduate School of Biomedical Science and Engineering.
