I obtained my Ph.D. from the Computer Science department at UT-Austin and was advised by Prof. Tandy Warnow and Prof. Keshav Pingali. My Ph.D. research was supported by an NSERC PGS award and Howard Hughes Medical Institute international student fellowship. My dissertation won the honorable mention for the 2015 ACM Doctoral Dissertation Award. More recently, I have been a recipient of the 2017 Sloan Research Fellowship in Computational & Evolutionary Molecular Biology, the NSF CAREER award, and the MIRA award from NIGMS at NIH. I contribute to many international projects and am part of the counsil of the Vertebrate Genome Project.

I am not offended by any pronouncination of my name, so, don’t worry about it. If you wonder, here is how I pronounce it. I have noticed that most native speakers are more comfortable staring my name with a Sh sound rather an S; so my only tip is, start with an S not a Sh and take it from there.


Mirarab lab focuses on computational biology with a specific focus on developing methods that target evolutionary analyses on large-scale datasets. These algorithms infer statistically rigorous estimates of evolutionary histories based on genomic data and use the results of such inferences in downstream applications. The techniques used range from classic algorithms (dynamic programming) to graph theory and statistical inference. More recently, we have started incorporating machine learning techniques that can integrate biological domain knowledge. High accuracy and scalability are the main focal points, with the idea that gains in scalability should not come at the expense of accuracy. While all the algorithms have heoretical underpinnings, much attention is paid to the empirical evaluation of methods under challenging conditions. The lab prides itself on developing many tools that are widely used by biologists (e.g., ASTRAL series) and have paved new directions (e.g., Skmer, DEPP). We strive to make these useful for biologists and often hold tutorials and workshops for providing training in the use of the tools. Biological applications explored by the lab include reconstruction of species trees from gene trees (phylogenomics), the study of biodiversity using low coverage genomic data (genome skimming), metagenomic analyses using phylogenetic and machine learning approaches, HIV transmission network reconstruction, and large-scale multiple sequence alignment. What unites these wide-ranging applications is their reliance on evolutionary trees as an underlying model.

I am proud of amazing students who have been in my lab.

  • Prospective students are generally discouraged from contacting me directly regarding admissions; those decisions are made by a committee in our department.
    In rare circumstances, if you have done work that is very closely related to my work, you can write to me and bring that to my attention.
  • Incoming and new students are encouraged to check out this page to learn about the background used in my work
  • ECE students without sufficient programming background may find this page useful.
