Younshim Park, Ph.D.

Postdoctoral Fellow

I received my Ph.D. from the University of Kansas Medical Center and conducted the research in the laboratory of Dr. Kausik Si located at the Stowers Institute for Medical Research. My doctoral studies were focused on regulatory mechanisms of intron retention during long-term memory formation. In the Perrimon lab I am interested in studying the functional role of protein isoforms in different biological systems.

Postdoctoral Fellow
I received my Ph.D. from NYU in the lab of Prof. Justin Blau, where I studied how circadian rhythms control neuronal structural plasticity. For my post-doc in the Perrimon Lab I am investigating the role of enteric neurons in intestinal regeneration.

Ankita Singh, Ph.D.

Postdoctoral Fellow

I received my Ph.D. in Molecular and Human Genetics under the supervision of Prof. Ashim Mukherjee from Banaras Hindu University, Varanasi, India. As a graduate student I got an opportunity to work on identification and functional characterization of novel interactors of Notch Signaling pathway in Drosophila melanogaster. As a post-doc in the Perrimon lab, I am interested to explore the mechanism of regulation of different signaling components and their cross-talk during development using molecular genetic approaches in Drosophila.

Baolong Xia, Ph.D.

Postdoctoral Fellow
I received my Ph.D. in Prof. Qi Zhou's lab at the Institute of Zoology, Chinese Academy of Sciences in 2017. My graduate work focused on pluripotency regulation and ploidy maintenance of embryonic stem cells. In Prof. Perrimon's lab, I am taking genome wide genetic screening to study molecular sensing and homeostatic maintaining in the negative entropy system of life.
Zhongjie Zhang, Postdoctoral Fellow

Zhongjie Zhang, Ph.D.

Postdoctoral Fellow
I received my Ph.D. from East China Normal University under the supervision of Dr. Kai Li and Dr. Anjiang Tan. My doctoral work involved genetic improvement of important economic traits of Bombyx mori using genome editing. In the Perrimon lab, I am interested in identifying new components of various signaling pathways using CRISPR screening and further exploring their roles.

Muhammad Ahmad

Ph.D. Student

I did my B.S. Biology from the School of Science and Engineering at Lahore University of Management Sciences where I studied starvation-induced dietary behaviors in Drosophila melanogaster. I am a Ph.D. student in Biology and Biomedical Sciences program at Harvard Medical School. For my Ph.D. in the Perrimon Lab, I aim to elucidate the hormonal control of energy homeostasis. Specifically, I am interested in understanding how metabolic hormones regulate the lipolysis of lipid droplets in Drosophila fat tissue cells. For this, I am employing cell based CRISPR-Cas9 screening as well as proteomics approaches.... Read more about Muhammad Ahmad

Matthew Butnaru, Ph.D.

Research Scientist
I received my Ph.D in biochemistry from Tufts University. In the lab of Dr. Marta Gaglia, I studied virus-host interactions and regulation of gene expression during Herpesvirus infection. In the Perrimon lab, I’m interested in using modern genomic tools to combat infectious disease and agricultural pests by leveraging insights from functional high throughput genomic screens. To this end, I am developing and optimizing cell lines and genetic tools for non-conventional model organisms, notably the Black-legged Tick (Ixodes scapularis) and the Corn Earworm (Helicoverpa Zea). Combining these novel tools with our lab’s genome-wide CRISPR screening platform, we aim to better understand essential genes and host-pathogen interactions. Upon identifying such genes, I aspire to develop more environmentally friendly and targeted methods to address these challenges.

Ben Ewen-Campen, Ph.D.

Research Associate
As an undergraduate, I studied developmental biology with Scott Gilbert at Swarthmore College. I then worked as a technician in Doug Emlen's lab at the University of Montana, studying the development of beetle horns, and in 2014 I received my PhD from Harvard University, working in Cassandra Extavour's lab on the embryonic specification of germ cells. In the Perrimon lab, I am studying long-range regulation of germline stem cell proliferation, and I am also interested in developing new tools for manipulating gene expression.
Karim Rahimi, PhD

Karim Rahimi, Ph.D.

Research Associate

Before joining the Perrimon Lab, I conducted extensive research on the function of microRNAs, circRNAs, and tRNA fragments in cancer, neuronal development, and neurodegenerative diseases. This was during my time as a Ph.D. student, postdoc, and later as an Assistant Professor at Aarhus University in Denmark (karimrahimi.com). In the Perrimon Lab, I systematically investigate the effectiveness of CRISPR-based tools for high-throughput gene knockdown and functional studies, which include Cas13 and CRISPRi approaches. Additionally, I employ Nanopore long-read sequencing to explore how epigenetic factors and DNA methylation influence gene expression profiles in drosophila. I study methods to write and erase such modifications for subsequent functional studies. 

Ram Viswanatha

Raghuvir Viswanatha, Ph.D.

Research Associate
I am intrigued by the dynamic regulation of subcellular compartments in eukaryotic cells. I got my Ph.D. from Tony Bretscher’s lab at Cornell University through studies of the dynamic spatial and temporal regulation of a key cytoskeletal protein, ezrin, by its kinase. Manipulating the dynamics led to the reversible, selective loss of a subcellular structure called microvilli. In the Perrimon Lab, I hope to use proteomics and functional genomics to obtain a detailed parts list for many more subcellular components with the goal of gaining broad insight into their formation, the regulation of their abundance and morphology, their evolution, and their involvement in tissue-specific cell functions.
