Iswar Hariharan Ishwar Hariharan

I obtained my degree in Medicine (MBBS) from the University of Sydney and my Ph.D. degree from the University of Melbourne where I worked with Jerry Adams and Suzanne Cory. My post-doctoral training was with Gerry Rubin at the University of California, Berkeley. I joined the faculty of the Massachusetts General Hospital Cancer Center and Harvard Medical School in 1992. In 2004 my lab moved to the Department of Molecular and Cell Biology at U. C. Berkeley where I am a Professor of Cell and Developmental Biology. I have no hobbies and have forgotten how to relax.

Jo Downes

I received my bachelor's in biology from UC Santa Barbara in 2011. It was at UCSB where I first dived into biological research, studying the sensual topic of nematode mating behavioral asymmetry in the laboratory of Dr. Joel Rothman. I joined the Hariharan lab in 2015, and my work delves into the role of cell adhesion in tissue growth. Outside of lab, I'm a proud member of Ravenclaw house, and I enjoy drawing and playing bass guitar.


Robin Harris

I completed my PhD in the lab of Dr Hilary Ashe at the University of Manchester in the UK in 2009, examining the differentiation of Drosophila germline stem cells, where I discovered my passion for awkward and repetitive dissection. I joined the Hariharan lab as a postdoc in 2011, and am currently studying the process of tissue regeneration by developing a screening system based on genetic ablation, which will ultimately allow the identification of genes that regulate regeneration. Aside from frequently indulging in larval wing disc dissections, I also enjoy running, yoga and going to the pub.

2012-2013: Postdoctoral Scholar, California Institute of Regenerative Medicine.
2013-2016: Postdoctoral Fellowship, Life Sciences Research Foundation.


Steven Reich

I joined the Hariharan Lab in April 2014 and work with Robin to investigate the genetic regulation of regeneration. I am currently studying the role of a particular enhancer in the repression of Drosophila regeneration over time and utilizing a Cas9/CRISPR genome editing technique. Outside of lab, I religiously watch European soccer games when not playing soccer myself, and I enjoy rooting for Bay Area sports teams.


Linda Setiawan

I am a graduate student at the Free University Berlin conducting my thesis project in Iswar's lab. During my Master studies in biochemistry, I felt a need to resurface from the subcellular and to study developmental biology in real animals. I did my Master thesis research in Didier Stainier's lab at UCSF studying the fate decision in liver/pancreas progenitors in zebrafish. In Iswar's lab, I study the mystery of genes involved in regeneration and have been conducting a genetic screen together with Melanie to address the burning question: Why do we regenerate less as we age?


Taryn Sumabat

I graduated from Stanford University in 2011 with a B.S. in Biology. There, my affinity for the Hippo pathway first took root, and I became interested in aspects of growth control while studying cell cycle dynamics in the lab of Dr. Jan Skotheim. Following graduation, I moved to Hong Kong to serve as a Princeton-in-Asia teaching fellow for one year. I then returned to California to pursue graduate studies at UC Berkeley, where I have been a member of the Hariharan lab since 2013. My work aims to understand the genetic and molecular coordination of tissue growth during development.

2014-2017: Graduate Research Fellowship, National Science Foundation (NSF).


Melanie Worley

I received my bachelor’s degree in biology from Massachusetts Institute of Technology in 2006 and learned that I am intrigued by both genetics and developmental fate decisions. I received my PhD from University of California, Berkeley in 2013 (in the Hariharan lab). I have now exhibited a fate change from graduate student to a post doc and am pursuing the identity of a mutant that enhances the frequency of transdetermination. I also developed a new technique to visualize and manipulate multiple clones, which we named "TIE-DYE", because we are in Berkeley after all. Besides in lab, I can be found outside searching for birds to add to my life list.

Won Jae Jeong

I am a third year undergraduate student majoring in MCB with Cell & Developmental Biology. I previously worked at the Song Lab in Korea University Medical College, studying the effect of BMP-2 on osteoblast activity; there I found my passion in biological science and research. I joined the Hariharan Lab in August, 2014. Currently, I am working with Justin on investigating a phenomena called Cell Competition in which certain cells affect the viability of adjacent cells and I enjoy working with Drosophila. Although I am originally from Korea, because I lived in Texas for 8 years I love saying "yall" while I hate saying "hella". I my free time, I like to ride cruiserboard, collect snapbacks, and watch 'How I met your mother' over and over again.



Hasti Mazdeyasna

I am a fourth year undergraduate student majoring in Molecular and Cell Biology, with an emphasis in Cell and Developmental Biology. I joined the Hariharan Lab in January 2016. Currently, I am working under Jo’s supervision to better understand how overgrowing Gal4 lines with oncogenes affect Drosophila wing discs. Outside of lab, I enjoy running, hiking, and hanging out with friends.


Susan Wang

I am a fourth year undergraduate student majoring in Molecular and Cell Biology, with an emphasis on Immunology. I am currently working under Taryn to better understand growth control mechanisms such as certain aspects of the Hippo pathway. In my free time, I enjoy volunteering, watching Youtube videos, and pondering the meaning of my life.
