Claudia Sanchez San Martin, PhD

I got my PhD in Biochemistry working with transcriptional regulation of some of the pathogenic genes of a fabulous bacteria: Enteropathogenic E. coli (EPEC). Then, I moved to the exciting virus world. As a Researcher at Universidad Nacional Autonoma de Mexico I had the opportunity to study the entry mechanisms used by rotavirus to infect cells, working with Drs. Susana Lopez and Carlos Arias. Then I did a postdoc at Albert Einstein College of Medicine (AECOM), with Dr. Margaret Kielian. I had the great pleasure to enjoy NYC and to work with alphavirus and flavivirus fusion glycoproteins. There, I studied conformational changes occurring during the fusion of viral and endosomal membranes. Then I worked at AECOM as an Instructor (which was something like a junior scientist there). Later, I moved to the Bay Area to get a new job. Here, I actually started two jobs: as a Mom and as an Assistant Professional Researcher at UCSF. For the last one I had the great opportunity to work with Dr. Charles Chiu and get into the NGS world . I recently joined UCB to work in this wonderful group. Here, I try to make everybody's scientific life easier, enjoy great science and aim to do more and more virus research

Marco Antonio Chapa

I am the lab manager for the Harris Lab. I received my Bachelors of Arts in Molecular and Cell Biology from UC Berkeley. This is my first position working within a research laboratory as my previous experiences range from working in clinical settings, as Medical Assistant and a Medical Scribe, to working as a teaching assistant for UC Berkeley’s Health and Medical Apprenticeship Program. In the Harris Lab I am responsible for overseeing administrative tasks and managing day to day operations within the lab.

Outside the lab, I enjoy running, hiking, attending/watching sporting events, and traveling home to spend time with my family.

Nharae Lee

I am a lab technician, focusing on the Focus Reduction Neutralization Test (FRNT) and virus production in the lab. I have graduated with a Bachelor of Science in Human Biology with Clinical Psychology from the University of California, San Diego. My prior research experience centers on the study of heparan sulphate's role in sepsis through work in a glycobiology lab, alongside positions at TEGA Therapeutics and Samsung Biologistics, where I specialized in the production of low molecular weight heparan sulphate and protein purification, respectively. Transitioning from the field of glycobiology, I am excited to explore the virology field, particularly in immunology, and contribute to research projects in the lab.

Outside of the lab, I am a huge esports fan and a gamer, but still enjoy basking under the sun and walking near the ocean.

Sandra Bos, PhD

I am a molecular/structural virologist specialized in the study of mosquito-borne flaviviruses. Navigating between Reunion Island and the Pasteur Institute of Paris, my previous work consisted in studying the molecular determinants of Zika's pathogenicity through the development of molecular clones and chimeras, targeting mutations in structural proteins. Alongside this, I also studied the impact of ZIKV on the maturation and the cytokine response of human plasmacytoid dendritic cells.

In the Harris Lab, I combine my background in structural virology & immunology to investigate the profile and functionality of the anti-DENV and anti-ZIKV humoral immune response. I am also the scientific coordinator of the project "Immune profiling of natural dengue virus infections" of the Dengue Human Immunology Project Consortium (DHIPC).

Outside the lab, I like cooking, get lost in worlds of SF or epic fantasy, and learn more virus stuff!

Tulika Singh PhD, MPH

I am an immunologist, virologist, and epidemiologist with a focus on human immunity and vaccines for emerging viruses. I conducted my PhD in the Laboratory of Dr. Sallie Permar at Duke University, and studied maternal antibody and B cell responses to Zika virus infection within a mother-infant prospective cohort from Brazil that I helped to establish. I identified a potent antiviral role for IgM antibodies and defined that Zika virus infection in pregnancy does not disrupt transplacental transfer of IgG antibodies. My Master of Public Health research focused on health service correlates of vaccine coverage in low- and middle-income countries and barriers to vaccine delivery. I completed a concentration in epidemiology and biostatistics and certificate in vaccine science and policy. As a scientist-advocate for better public health, I serve on the Board of Right to Health Action (non-profit) and speak up on global vaccine equity and pandemic prevention issues to shape a healthier future with science.

In the Harris Lab, I investigate cellular correlates of protection from symptomatic Dengue disease to delineate B cell underpinnings of the dual risk and protection mediated by dengue-reactive antibodies. Understanding the cellular mechanisms behind human immune protection against dengue disease will guide dengue vaccine design and development.

Felix Pahmeier

I am a molecular virologist from Northrhine-Westphalia, Germany. I conducted my undergrad studies at Muenster University (Germany) and NTNU Trondheim (Norway) where I investigated co-infections of S. aureus and Influenza A virus. I also have an MSc in Molecular Biosciences with the major Infectious Diseases from Heidelberg University where I undertook research on several RNA viruses (Bunya-, Flavi- and Coronaviridae) and developed a great interest in virus-host interactions and investigation of mechanisms underlying human disease.

My graduate studies will focus on virus-host interactions of NS1 with human endothelial cells and development of tools to study NS1 role in dengue pathogenesis.

Outside the lab, I like spending time hiking and biking in nature as well as exploring the diverse culinary culture of the Bay Area

 

Pedro Carneiro

I am a biologist working in the virology field for the last 10 years, with a focus on virus-host interactions. I’ve been studying viral pathogenesis for the development of antiviral therapeutics.

In the Harris Lab, I’m a visiting scholar on an internship program during my PhD, studying molecular inhibitors of flavivirus NS1 protein.

Outside the lab, I like watching tv shows, eating, drinking and partying with friends.
