Current Lab Members


Jacob Paiano, Ph.D.

Postdoctoral Fellow
I received my PhD in immunology at the University of Pennsylvania, although I completed my thesis at the National Institutes of Health in Bethesda, MD. In the lab of Dr. Andre Nussenzweig, I developed next-generation sequencing methods to study DNA damage and genome integrity during cell division. In the Perrimon Lab, I am interested in studying inter-organ communication networks that coordinate organismal stress responses.

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.

Afroditi Petsakou

Afroditi Petsakou, Ph.D.

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.
Pedro Saavedra

Pedro Saavedra, Ph.D.

Postdoctoral Fellow
I received my Ph.D. in Developmental Biology from the University of Cambridge, UK, under the supervision of Dr Peter Lawrence and Dr Isabel Palacios. I used the Drosophila larval epidermis to study the link between planar cell polarity and patterning of tissues during development. Then I had a brief stint in Dr Steven Cohen lab in the IMCB, Singapore, to study how microRNA regulate metabolism and growth. In the Perrimon Lab, my research is focused on muscle degeneration. In particular, I am studying the cellular and molecular mechanisms involved in muscle wasting during cancer-induced cachexia.

Ankita Singh

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.

Sudhir Tattikota

Sudhir Tattikota, Ph.D.

Postdoctoral Fellow
I earned my Ph.D. from the Max Delbrueck Center for Molecular Medicine, Berlin, Germany, where I studied the role of the microRNA pathway in maintaining the function of pancreatic beta cells. Using several cellular and mouse model systems, I could demonstrate how Argonaute2 regulates secretome and proliferation of the beta cells. As a postdoc in the Perrimon Lab, I am integrating emerging technologies including CRISPR and single cell transcriptomics to delineate mechanisms governing blood cell homeostasis and characterize novel blood cell populations in Drosophila. In the future, I aim to focus on immunometabolism by understanding the dynamics of hematopoiesis during disease states such as Diabetes and Cancer. My other activities include running 10Ks, besides just running gels in the lab.
Ram Viswanatha

Raghuvir Viswanatha, Ph.D.

Postdoctoral Fellow
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.
Baolong Xia

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.

Jun Xu, Ph.D.

Postdoctoral Fellow
I received my Ph.D. from Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences under the supervision by Dr. Yongping Huang and Dr. Anjiang Tan, where I studied the sex determination and spider silk production by using silkworm as a model. In the Perrimon Lab, I want to establish new immunological methods to dissect the inter-organ communication network with high sensitivity.
