Profile

Qualifications

Ph.D. Computer Science, University of Manchester, United Kingdom.

M.Sc. Embedded Systems, University of Manchester, United Kingdom.

B.E. Electrical Engineering, National University of Sciences and Technology, Pakistan. 

Experience

Some of the interesting areas where I have practised my skills are machine learning, simulation, real-time systems, image processing, and software development. I have used these skills for seismic data processing, telecommunication records processing and profiling, call queues management, and developing decision support systems.

Research

My research interests lie in data mining, machine learning and decision support systems. Some of my recent projects involved the use of text analytics, dominance-based rough sets analysis, imbalanced classification and visual aids. I am also interested in the theory and applications of multi-criteria decision analysis wherein decision makers often struggle to optimize or satisfice multiple objectives where some of these objectives are often in conflict with each other.

Teaching

I have been involved in the following modules in Leeds University Business School in different roles:

  • LUBS5586 Quantitative Analysis I led this module from 2015 to 2017 and mentoring other staff members since 2017. In this module, I give students a sound grounding in quantitative analysis at the level necessary to facilitate their study of academic literature on their MSc programme and to allow them to use and interpret results in a business environment.
  • LUBS5318 Evidence-based Consultancy I am leading this module since 2015. In this module, I provide students with the skills to act in a consultancy capacity for both external and internal clients in a commercial context. They learn how to use structured approach towards problem diagnosis, solution development, and presenting to managers as well as stakeholders.
  • LUBS3200 Business Analytics 3 Analytics Project I was the module leader for this module from 2017 to 2018. In this module, I helped students to undertake an independent analytics project, write-up a project report, and reflect on their professional and personal development.
  • LUBS2940 Business Analytics 2 I was the module leader from 2017 to 2018 and now acting as a mentor. In this module, I taught about how businesses and other organisations use data analytics to support an evidence-based approach to management decision making.
  • LUBS2931 Evidence-based Consultancy I am leading this module since 2016. In this module, I provide students with the skills to use structured approach towards problem diagnosis, solution development, and presentations for managers.
  • LUBS1086 Exploring Your Potential I acted as the personal tutor for Business Analytics cohort from 2017 to 2018. I was involved in delivering seminar classes for this module and other related activities.
  • LUBS5582M Research MethodsI delivered seminar classes for this module from 2015 to 2016. The aim was to give students a sound grounding in research methods in order to facilitate their undertaking of a dissertation project, as well as, to allow them to use and evaluate research methods in a business environment.
