Kemal Achour
Specialist
Kemal is an assistant specialist in optics in the ABC lab since November 2023, he is very excited about working with lasers and microscopes ! In his free time, Kemal loves exploring and visiting new places and he also loves watching and playing football (or soccer here I guess…)
Eric Betzig, PhD
Co-Founder
After going to Caltech for undergrad, Eric did a PhD at Cornell with a thesis on the development of near-field optics – the first method to break the diffraction barrier in light microscopy. His work has revolutionized the industry from his Nobel Prize winning PALM technology to his latest work on LLSM and AO applications.
Xavier Darzacq, PhD
Co-Founder
Xavier received his BS at Ecole Normale Supérieure (Paris), his Masters & PhD at Université Paul Sabatier (Toulouse) and performed his postdoctoral research at Albert Einstein College of Medicine, with Robert Singer. Xavier’s enjoys kayaking when not performing research. Tjian + Darzacq group studies transcription, focusing on the role imposed by nuclear architecture on the molecules regulating it. They use a model system of cellular differentiation of human primary dermal fibroblasts into myofibroblasts, which is relevant to wound healing. Among the specificities of this system, they show that the maintenance of the fibroblast state depends on a specialized non-canonical mediator complex, which is becoming one of the central projects of the group.

Marianne Harrison
Lab Admin
Marianne studied English and Social Geography in her undergraduate education at Berkeley but was drawn to the industry of lab management from the start of her professional career. She is the proud mother of 3 children and additionally the whole lab. In essence her work ensures that the researchers are able to perform their tasks with ease and all operations of the lab run smoothly.

Doug Koshland, PhD
Executive Director
Doug received his bachelors in Chemistry from Harverford College, his PhD at Massachusetts Institute of Technology, and performed his postdoctoral research at University of Washington with Leland Hartwell and University of California, San Francisco with Marc Kirschner.
His laboratory uses budding yeast to study fundamental processes in cell biology. Their approach has been to develop novel genetic reagents and cell biological methods to analyze these complex processes in vivo, coupled with the development and exploitation of in vitro assays to reveal underlying molecular mechanisms.

Gaoxing Liu, PhD
Postdoctoral Researcher
Gaoxiang obtained his Bachelor in Chemistry at Fudan University, China. He then went to Johns Hopkins University, where he studied gas-phase clusters by photoelectron spectroscopy. After getting his Ph.D in Physical Chemistry at Johns Hopkins University, he decided to transfer from researching the invisible and untouchable gas-phase clusters to studying real-world biological dynamics with the best optical tools. At ABC, he is responsible for constructing and operating the MOSAIC microscope. When not at work, he enjoys going to the gym and watching movies.
Matthew Mueller
Staff
Matthew received his B.S. from the University of California, Irvine. Anything related to computers, you can bet he’ll have a hand in helping out. He joined the lab in January 2021 as part of the computational staff and hopes to make an impact through his expertise in optimization and high performance computing.
Xiongtao Ruan, PhD
Postdoctoral Researcher
Originating from his roots in China, Xiongtao came to the US and got a PhD from Carnegie Mellon University advised by Robert Murphy in computational biology. He hopes to develop novel bioimaging solutions which allow for higher resolutional analysis of in vivo biological samples as they are imaged by the lab’s MOSAIC microscopes. You can find him playing table tennis or running when he is outside the lab.

Robert Tjian, PhD
Co-Founder
Tij received his BA at University of California, Berkeley, PhD from Harvard University, and performed his postdoctoral research at Cold Spring Harbor Laboratory with James D. Watson. Tij as an avid fly-fisherman. Tjian + Darzacq lab studies biochemistry of transcription and chromatin transactions, and has identified, isolated and characterized a large number (~100) of essential drosophila and human transcription factors. These regulatory proteins include enhancer/promoter recognition factors, core RNA pol II initiation factors and co-activators that form large multi-subunit complexes at promoter DNA to mediate transcription initiation and decode the genome.

Gokul Upadhyayula, PhD
Scientific Director
Gokul received his BS at University of California, Irvine; his Masters & PhD at University of California, Riverside and performed his postdoctoral research at Harvard Medical School with Tomas Kirchhausen. Gokul’s research interests bridge applied engineering with basic science. His earlier work includes studying the charge transfer properties of cyanine dyes and bioinspired electrets using ultra-fast femtosecond spectroscopy during his time at University of California, Riverside; and using lattice light-sheet microscopy (LLSM) with high temporal and spatial resolution at the molecular level during his postdoctoral research at Harvard Medical School / Boston Children’s Hospital. Gokul is interested in mechanistic questions addressed at a molecular level by fluorescence microscopy imaging acquired with high temporal and spatial resolution. As the scientific director at UC Berkeley’s Advanced BioImaging Center (ABC), Gokul’s vision is to provide state-of-the-art microscopy, and dedicated human and hardware resources capable of handling terabyte to petabyte scale projects. In addition to this, his mission is to develop robust, open source computational workflows that allow scientists to extract biologically meaningful insights.
