Meet The Team

Tiffany Amariuta, PhD

Principal Investigator

Tiffany started her group at UCSD in July of 2022. For more information about her and the research focus of the group, please see the home, about, and publications pages.


Ziqi Xu

PhD student

Ziqi is currently a first-year PhD student in the Bioinformatics and Systems Biology (BISB) program. Her research interest lies in developing computational and statistical methods to understand genetic contributions to diseases. Her current project focuses on estimating heritability from single cell gene expression data and investigating co-regulation across genes and cell types using GWAS and single-cell RNA-seq data. Ziqi enjoys spending her spare time in dog parks and zoos.

Kuan-Hung (Peter) Yeh

PhD Student

Peter is a first year graduate student in the Bioinformatics and Systems Biology (BISB) PhD program. He is interested in developing statistical models for the integration of genetic data across diverse populations, with a specific interest in gene-level disease risk. During his free time, Peter enjoys baseball, basketball, hiking, and wine tasting. 

Alona Korzhakova

Computational Data Science Researcher

Alona has previously worked as a software engineer at NVIDIA and is currently working with our team to design user friendly applications for deploying our genetic and genomic tools into the community. In her spare time, Alona enjoys going to the beach. 


Kai Akamatsu

Undergraduate Researcher

Kai is a second-year undergraduate student studying Bioinformatics. He is currently working on multi-ancestry gene expression prediction models. His goal is to leverage computer science to democratize high-quality medicine and improve patient care outcomes. In his free time, Kai likes to surf with his friends and cook.


Sivani Vedula

Undergraduate Researcher

Sivani is a second-year undergraduate student studying Bioinformatics. She is currently involved in a single-cell causal inference project and is studying gene expression prediction models. She aims to employ the intersection between computational models and genetic studies to contribute to improving disease prognosis and treatment. Sivani enjoys making music and reading.


Sujana Sreenivasan

Undergraduate Researcher

Sujana is a second-year undergraduate majoring in Bioinformatics with a minor in Computer Science. Her current project involves using machine learning strategies to identify genome-wide regulators of gene expression. Her goal is to utilize computational tools to contribute to genetic disease therapy. In her free time, she enjoys cooking, movies, and exploring new cities.
