Researchers

Yang Liu, Ph.D.

2020 Ph.D., Chemistry, University of Georgia

2014 B.S., Chemistry, Purdue University y of California, Berkeley

During his Ph.D. studies, Yang developed state-of-art circulating tumor cell (CTC) and exosome isolation devices with ultra-high throughput and resolution. During his Postdoctoral Fellowship, Yang is moving forward to make protein analysis of key cancer biomarkers possible. Yang has a chemistry degree, but he considers his research contributions to be “non-chemistry”.

Hyekyung Lee, Ph.D.

2020 Ph.D. Seoul National University

2015 M.S. Chemical Engineering, Seoul National University

2012 B.S. Applied Chemical Engineering, Pusan National University

During her previous research, Hyekyung investigated the effects of geometric modulation on permselective ion transport and developed the fundamental understanding of nano-electrokinetics. Now in her Postdoctoral Fellowship, her research focuses on improving detection sensitivity and reducing dispersion in single-cell protein detection. Although she is Korean, she cannot eat spicy food, even kimchi. She loves plants and backpacking.

Alison Su, Ph.D.

2021 Ph.D. Bioengineering, UC Berkeley/UCSF Graduate Program in Bioengineering

2013 BA Engineering Sciences and 2014 BE, Dartmouth College

Ali engineers accessible measurement tools and workflows for biomedical applications ranging from bench to bedside. Examples include an imaging and analysis pipeline to measure 3D partitioning of solutes in hydrogels, and a method to quantify color change of photochromic indicators for validation of UV-C decontamination of N95 respirators during the COVID-19 pandemic. When she’s not doting on her miniature poodle, Ali enjoys referring to her mugs of hot chocolate as coffee.

Anna Fomitcheva Khartchenko, Ph.D.

2020 Ph.D., Chemistry and Applied Biosciences, ETH Zurich, Switzerland

2016 M.Sc., Biomedical Engineering, ETH Zurich, Switzerland

2012 B.Sc., Cellular and Molecular Biotechnology, Autonomous University of Barcelona, Spain

Anna’s interests lie in developing technologies which aid the diagnosis and understanding of human disease. Particular interest is in profiling tumors and improving diagnostic methods to understand and predict the behavior of cancer. She aims to design technologies for improving immunoassay performance, which can underpin more sensitive and precise diagnostic tools.

Alden Moss

UC Berkeley Lewis Scholar

2017 BS Bioengineering, Minor in Chemistry, Minor in Spanish, Oregon State University

Alden is focused on improving the sensitivity of single cell proteomic assays through the use of DNA-based readouts, working toward the ultimate goal of highly sensitive duel measurements of proteins and nucleic acids. Outside of the lab, you can find him cruising around in the Berkeley Hills on his bike, experimenting in the kitchen, and exploring new places.

Louise L. Hansen

UC Berkeley Lloyd Scholar & Graduate Remote Instruction Innovation Fellow

2017 BS Bioengineering, University of Washington, Seattle

To interrogate the conversion of extracellular matrix cues into proteomic programming, Louise is developing new measurement tools for high-specificity, single-cell cytoskeletal evaluation. In collaboration with Julea, she is improving the molecular specificity with which we measure cytoskeletal integrity by detecting protein complexes. Louise keeps her family & friends up to date with handwritten mail, so they’re always 3 days behind on news.

Ana E. Gomez Martinez

NSF Graduate Research Fellow, GEM Full Fellow, Frank Shwabacher Graduate Fellow

2018 BS Bioengineering, University of Washington, Seattle

Ana develops tools to measure DNA (damage or sequence) and protein expression from the same individual cells. She likes trying new food and desserts and running in the Berkeley Hills.

Gabriela Lomeli

NSF Graduate Research Fellow, GEM Associate Fellow, UC Berkeley Brodie Scholar, & UC Berkeley Lloyd Scholar

2018 BS Chemical Engineering, Minor in German Studies, Stanford University

Gabriela is focused on advancing our ability to study multiple protein isoforms at the single cell level through advancements in microfluidic and mass cytometry imaging tools. She enjoys embracing her Gen Z tendencies and convincing people orchids are still worth keeping after their flowers wither.

Yaw Ofosu Ansong Jnr, M.D.

CIRM Research Scholar, UC Berkeley Brodie Scholar

2015 M.D., University of Cape Coast

2019 M.S., Biomedical Engineering, University of New Haven

Yaw is currently developing tools to help jointly measure mRNA sequences and corresponding protein isoforms in single cells.  He is interested in applying basic engineering to solve relevant clinical problems for low resource settings and is an entrepreneur at heart.

Daniel Baron, Ph.D.

2019 Ph.D., Analytical Chemistry, Palacký University, Czech Republic

2014 M.S., Analytical Chemistry, Palacký University, Czech Republic

2012 B.S., Chemistry, Palacký University, Czech Republic

Daniel’s research interests include electromigration techniques, on-line pre-concentration, analysis and characterization of nano-objects, mass spectrometry, and hyphenated techniques. He is a visitor to the Herr Lab through the support of the government of the Czech Republic.
