Former Members of C. C. Wang Lab

Sin-Fu Tzeng

Along with Peng Wu I work on our group's T. vaginalis project. I'm purifying the purine nucleoside kinase enzyme and hope to find an inhibitor of this key metabolic checkpoint in the parasite.

Before joining the Wang lab I started the biotech company BioCheck, which makes test kits for diagnosing heart disease, colon and breast cancer.


Peng Wu

As a protein chemist I'm measuring the activity of a battery of T. vaginalis purine nucloside phosphorylase mutants that I've created. By screening these mutants I hope for a better understanding the mechanism of the enzyme, leading to better drug treatments against the parasite.

I came to the group from USC, where I specialized in using the electron paramagnetic resonance technique to analyze protein structure. When not in the lab I enjoy photography and playing weiqi, also known as go.


Praveen Kumar

I study the role of the subunits of the Anaphase Promoting Complex in T. brucei using RNAi and tandem affinity protein purification. I come to UCSF from Jawaharlal Nehru University in Delhi, and when not in the lab enjoy movies and travel.


Lei Li

I study the role of the 5' mRNA cap structure in translation initiation in Giardia. I came to UCSF from Beijing University. When not in the lab I enjoy playing with my son Lucian, who is 17 months old and the apple of my eye.


Xiaoming Tu

I use RNAi to investigate homolgues of cyclin-dependent kinases in Trypanosoma brucei. My interests away from the lab include music and badminton.


Jennifer Sherwood

Trichomoniasis, caused by the flagellated protozoan Trichomonas vaginalis, is the most common sexually transmitted infection. It is associated with increased preterm delivery, cervical cancer and heightened risk of HIV/AIDS. The purine salvage enzymes of T. vaginalis are promising chemotherapeutic targets because the organism must recycle purines from its human host for survival. I work on purine nucleoside phosphorylase (PNP), a pivotal enzyme in the organism's purine salvage pathway. Guided by clues from X-ray structures of human and parasite PNP and PNP-inhibitor complexes, I carry out kinetic assays of bacterially expressed T. vaginalis PNP mutants to determine substrate specificities and catalytic properties of the enzyme. This information will be useful for generating selective, potent anti-trichomoniasis chemotherapeutic agents.

When not pursuing my goal of discovering an anti-parasitic drug, I enjoy training for marathons and ironperson triathlons.


Arti Gupta

I work on the purine nucleoside kinase system in the parasite Trichomonas vaginalis. I want to clone the enzyme and find an inhibitor of this key metabolic checkpoint. I did my PhD research on isoprenoid metabolism in the malaria parsite P. falciparum at the Central Drug Research Institute in Lucknow.

My hometown is Bijnor, in Uttar Pradesh State. When I'm not in the lab I enjoy drawing portraits and reading.


Jason Savich

As a Research Assistant in the Wang lab I do proteasome purification, and use RNAi to investigate cyclins. I came to UCSF from Georgetown University. Away from the lab my interests include music and art.


Wen-Hu Wang

As a protein chemist I look at the 20S and 19S proteasome subunits in T. brucei, and the purine nucleoside phosphorylase and kinase in T. vaginalis. I enjoy soccer and other ball sorts, and reading.


Christine Wu

I'm a fourth year graduate student in the School of Pharmacy. I work on the purine nucleoside phosphorylase system in the parasite Tritrichomonas vaginalis and hope to help find an inhibitor of this key metabolic checkpoint. I came to UCSF from Grinnell College. When I'm not working in the lab I like to talk to my friends on the phone.


Anne E. Sarver

I am currently a 5th year graduate student in Chemistry and Chemical Biology. My thesis work deals with an essential purine salvage enzyme and potential chemotherapy target, the Adenine Phosphoribosyltransferase (APRTase) from the parasite Giardia lamblia . My undergraduate work was done at the University of Minnesota, Twin Cities in Chemistry and Biochemistry.


Alice Wang

My main interests in the lab are Giardia lamblia and giardiavirus. When I'm not working on these organisms I'm the lab manager. And in my free time I enjoy conversing with pandas!
