2014-04-25-Prof Michael Brudno. Computer Science

Dr. Michael Brudno, Scientific Director

Michael was raised in a family of mathematicians and programmers who gave him puzzles to solve since kindergarten. After receiving his BA in Computer Science, he proceeded with the completion of his PhD at Stanford University in California where he worked on algorithms for whole genome alignments. His contributions include co-authoring over 60 peer reviewed research papers, developing approaches for comparison of genomic sequences, teaching at the University of Toronto, and working at the Hospital for Sick Children where he is the Director of the Centre for Computational Medicine. Michael’s research interest is the development of computational methods for the analysis of clinical and genomic datasets, and the analysis of High Throughput Sequencing data. Aside from Science, his other passions include playing soccer, hiking, skiing, and spending time with his family.

Dr. Yue Jiang, Research Associate

Yue has been a big fan of computer science since college. He spent two years in the research lab at the University of Toronto as a visiting PhD student where he worked on indel detection algorithm development. This is where his interest peaked for the bioinformatics and computer science field. After he completed his PhD from Harbin Institute of Technology in China, he was invited to do post-graduate research work at SickKids. He now works on the analysis of DNA sequencing and RNA sequencing data of cancer genome under Dr. Brudno’s supervision. Yue is a computer games enthusiast, and he plays basketball, ping-pong and swims to keep fit.



Justin Foong, Sr. Bioinformatician

Justin received his masters in computer science from the University of Toronto. He is currently a bioinformatician at the Hospital for Sick Children. He is interested in computational analysis methods and their application to clinical and genomic datasets.



Dorin Manase, Bioinformatician

Dorin graduated with a BSc in computer science and cells and systems biology from the University of Toronto. Keen on pursuing a career at the intersection of both majors, he joined SickKids as a Bioinformatician in training in 2012. After a few years of research experience in genetics and genomics, he recently moved to the Center for Computational Medicine with a desire to further his computational skills. On his own time, Dorin enjoys playing soccer and helps coach at the University of Toronto.


Dr. Sam Khalouei, Bioinformatician

Sam received his Hon.BSc. from the University of Toronto in Computer Science and Human Biology and his MSc. from the University of Ottawa in bioinformatics. He then moved back to the University of Toronto to complete his PhD studies. During postdoctoral fellowship,  Sam carried out next generation sequencing library preparation and also implemented a bioinformatics pipeline. He joined the CCM team in July 2016 and has been involved in different tasks such as optimization of bioinformatics pipelines and analysis of genetic variation data. In his spare time Sam enjoys reading, drawing and painting.


Dr. Sergey Naumenko, Research Associate

Sergey received B.Sc and M.Sc in Computer Science from Kharkiv National University of Radio and Electronics (Kharkiv, Ukraine). Then he joined the sector of nonlinear dynamics in Keldysh Institute of Applied Mathematics (Moscow, Russia), where he studied self-reproducing cellular automata, DNA computing, models of the evolution of early life and the origin of genetic code. In KIAM Sergey also taught a course on Biology Inspired Computing.
Sergey worked on PhD project and defended PhD thesis in the joint laboratory of Evolutionary Genomics (Moscow State University, Russia) and Molecular Evolution (Institute for Information Transmission problems of Russian Academy of Sciences, Moscow, Russa) lead by Alexey Kondrashov and Georgii Bazykin He studied patterns of molecular evolution of protein-coding genes in mammals and insects (epistasis, homoplasy in phylogenetic trees), and inferred the phylogeny of lake Baikal Gammarid species flock using de-novo assembled transcriptomes. Also Sergey was involved in system administration of HPC for NGS data processing in the lab.
During several years Sergey taught Linux Administration and Parallel programming courses in D.Mendeleyev University of Chemical Technology of Russia (Moscow, Russia), and co-organized ACM-style programming contests for students.
At CCM Sergey is helping clinical researches to investigate molecular causes of rare diseases using WES, WGS, and RNA-seq data analyses: he produces annotated small variant reports for genome and exome analysts in Care4Rare project using WES and WGS data; calls and annotates structural variants using WGS data; performs expression outlier, aberrant splicing, small variant analyses using RNA-seq data. Sergey is specializing in using bcbio ( sequencing analysis toolkit.
