Research Focus

​The Signal Processing and Computational Biology Group is an interdisciplinary research group in the Department of Electronic and Computer Engineering at The Hong Kong University of Science and Technology (HKUST). We focus on developing high dimensional statistical and machine learning methods, and applying them to problems in signal processing and computational biology. Our group also works on the theory and applications of random matrices.

News

April - May 2020

We have developed a web-based platform, "COVIDep", for real-time reporting of vaccine target recommendations for the COVID-19 coronavirus (SARS-CoV-2). Main features:
  • Identification of SARS-derived B-cell and T-cell epitopes that provide vaccine target recommendations for SARS-CoV-2;
  • For T cell epitopes, it reports estimated population coverage using HLA/MHC statistical information;
  • Intuitive graphical interface with flexible parameter setting;
  • Up-to-date reporting based on latest sequence data available (from GISAID).

See the bioRxiv preprint: "COVIDep: A web-based platform for real-time reporting of vaccine target recommendations for SARS-CoV-2" 

​Saqib and Ahmed's paper, "How genetic sequence data can guide vaccine design", has been published in IEEE Potentials Magazine.

Neil, Faraz, and Awais shared their experience as international PhD students at HKUST in a Study International article.
