Principal Investigator


Allison Lopatkin

Assistant Professor
Dept. of Biology
Barnard College, Columbia University

About Me:
I am formally trained in Applied Mathematics from University of Rochester. I then went on to get a PhD in Biomedical Engineering from Duke University, and completed my postdoctoral training at MIT/Broad Institute in the lab of Jim Collins. When I'm not in the lab you can find me hiking anywhere outdoors, or playing with my dog Tiki (who refuses to hike).

Lab Members


Jenifer Moralez

Research assistant

I am a senior from Texas majoring in Neuroscience and Behavior. I am President of the Barnard Network of Pre-Medical Students, a Senior Interviewer and a guitar player. I am interested in human health, specifically the biological processes that occur everyday in our body to keep us healthy. I am eager to learn more about how infection resistance works and apply this knowledge to advance public health.


Alana Palomino

Research assistant

I am a rising junior majoring in Cellular & Molecular Biology. In addition to being a member of the Lopatkin Lab, I am an executive board member of the Columbia Science Review and I play for the Columbia Field Hockey team. In the lab, I’m interested in working towards preventing the spread of antibiotic resistance as it becomes an ever-growing threat to global health, first by understanding what influences HGT.


Hannah Prensky

Research assistant

Hannah is a rising junior at Barnard majoring in Cell & Molecular Biology and Economics. She is passionate about biological research and has a particular interest in genomics, nucleic acid nanotechnology, and gene editing for therapeutic purposes. In addition to her love of lab research, Hannah enjoys engaging with the scientific community through her positions as a journalist with the Columbia Science Review and as a developmental editor with the Columbia Undergraduate Research Journal. When she’s not in the lab, you can find her in the mountains skiing with the Columbia Ski Team.


Ujana Zajmi

Research assistant

I am a rising third-year at Barnard, and I am pursuing a B.A. in Cellular and Molecular Biology. I was previously involved in research studying dauer formation in C. elegans at the Hobert Lab at Columbia University, and I am very excited to now be exploring antibiotic resistance with the Lopatkin Lab. In my free time, I enjoy oil painting and graphic design!
