A small introduction about my self

Nasir Mahmood, PhD

Data Scientist & Bionformatician

Nasir is a computer scientist specializing in machine learning, natural language processing (NLP), and big data. He has a strong interdisciplinary background in computer science, statistics and bioinformatics. These experiences have provided him with a unique perspective to successfully tackle new projects in a diverse range of areas. In addition, his extensive involvement with interdisciplinary teams, in both industry and academia, has been a great source of pride and inspiration that has helped him to expand his knowledge and develop his skills further.

Nasir is what you’d call a lifelong learner. He’s always reflecting on the lessons learned from the past as a tool to help him grow. This has led to a strong belief that mistakes are simply opportunities to learn and grow. It’s these failed attempts in life that have helped to mould him into the successful entrepreneur that he is today.

His mind is always turning over new ideas and some of his best thoughts come to him in the middle of the night while most people are winding down for the evening. It’s a never give up, progressive, and forward thinking attitude that has made him the success he is today. Nasir lives with his wife, two sons, and daughter and they are the inspiration and motivation that drive him every day to push the limits of what he 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.
