Nasir Mahmood - Data Scientist and Mentor

Hi i am Nasir Mahmood

AWS Certified Machine Learning Engineer

I bring 15+ years of data science and machine learning experience, with 8 years in banking, insurance, and marketing.

I help businesses to leverage the power of DATA by reducing COST and increasing EFFICIENCY - ACCELERATED GROWTH.

I live in Canada with my wife, two sons, and daughter. They are the inspiration and motivation that drive me every day to push the limits of what I can achieve.

2006-2010

Education

University of Hamburg, Germany

PhD, Computational Biology

During PhD research I worked on protein structure prediction, a classical probelm from computational biology. I developed low-resolution coarse grain force fields, which do not involve physical model or Boltzmann statistics. They rather use a mixture of Bayesian probabilities from normal and discrete distributions of features of known proteins. Consequently, a ratio of probabilities provides acceptance criterion for Monte Carlo method in prediction simulations. For more details, please check out my doctoral dissertation and presentation slides.

2005-2006

Education

Cologne University Bioinformatics Center, Germany

Postgrad. Diploma, Applied Bioinformatics

During 1-year instensive program, I worked on a mandatory research project (in addition of course work) with focus on protein structural alignment, an NP-hard problem. I analyzed performed of existing algorithm and then modified by advancing optimization step. My contribution led to a significant increase in overall algorithm performance. Also, I benchmarked new algorithm against existing methods. For more details, please check out my project report and presentation slides.

2004-2007

Education

Otto-Von-Guericke University, Magdeburg, Germany

M.Sc. Computational Visualistics

During research thesis, I worked on implementation and benchmarking of a document retrieval system for a handwriting device - PC Notes Taker (PCNT). PCNT device is believed to be competitive compared to other device which we had already tested and benchmarked. I extended features of the document retrieval system by implementing a subtype of triangular grid features and compared its results with those of existing features. It was found that new features were slightly poorer but closer to square grid features. For more details, please check out my master thesis and presentation slides.
