Signal Processing & Computational Biology

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

Saqib’s paper “Fitness inference from complex evolutionary histories with genetic linkage” has been accepted for publication in Nature Biotechnology. This is a joint work with Raymond Louie (University of New South Wales) and John Barton (University of California-Riverside).

Matthew has been selected to contribute to the 2020 world laureates forum as a young scientist.

Preprint of our recent COVID-19 related work “Epitopes targeted by T cells in convalescent COVID-19 patients” has been posted on bioRxiv. As a part of this work, we have developed a web-dashboard that provides an up-to-date information of the emerging data of SARS-CoV-2 T cell epitopes targeted in convalescent patients.

June 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).

An article related to the platform “COVIDep: a web-based platform for real-time reporting of vaccine target recommendations for SARS-CoV-2” has been published in Nature Protocols. 

Highlighted on the cover page of Nature Protocols (July issue).

Related bioRxiv preprint: “COVIDep platform for real-time reporting of vaccine target recommendations for SARS-CoV-2: Description and connections with COVID-19 immune responses and preclinical vaccine trials“.

May 2020

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.

February – March  2020
