Location of work: Matrikon Inc. and Department of Chemical and Materials Engineering (Rm 280A)

Personal Details: I was born in a lovely lush green village, Hajigonj Bazar, located in the district of Lalmonirhat in the northern region of Bangladesh. Since I have been grown up in a rural area, my childhood was not spoiled with the heavy burden of studying a large number of books. I used to go to school only for few hours and study another couple of hours. I enjoyed my childhood in doing many interesting things such as fishing, swimming in ponds and rivers, plucking flowers, gardening, playing soccer, cultivating barren lands, planting trees, and repairing bamboo. By the way I still enjoy fishing and go for fishing in Wabamun lake, Hasse lake, spring lake and many other Alberta lakes.
After enjoying a colorful childhood and a semi-notorious juvenile time, I moved to Bangladesh University of Engineering and Technology (www.buet.ac.bd) to receive my training in Chemical Engineering. Here I started feeling the pressure of engineering education. I graduated from this university with ranking one in my class and was awarded a gold medal for outstanding achievement in my Bachelors degree. I also received a Masters degree in Chemical Engineering from the same university. I worked as a lecturer in the Department of Chemical Engineering of Bangladesh University of Engineering and Technology (BUET) from 1996 to 1998. During this appointment I enjoyed teaching, designing experiments and conducting undergraduate laboratories.

In 1999, I arrived at the University of Alberta to pursue my PhD degree in the area of Process Control. I was awarded PhD in process control in the summer convocation of June 2005. The PhD years have been very productive and fruitful to me. I received many prestigious awards such as Dissertation Fellowship, Andrew Steward Memorial prize, ISA educational foundation scholarship, etc. An international patent is in process on “Methods for detection and quantification of stiction in control valves”, which is the core work of my PhD dissertation. More importantly during the PhD period I got married with Shuma and God blessed us with our first son, Mahdi.

I was awarded an Alberta Ingenuity (AI) Industrial Fellowship on the same day Mahdi was born. I worked as an AI fellow for the period of December 2004 to November 2006. In February 2006 we have been gifted with another son, Muttaqi. Since then my schedule has been very hectic for continuing my work and maintaining a sound family life with a working wife and two little kids. I forget all my tiredness when I see the cute smiles of my two wonderful sons.
Having trained in a ground-breaking research group, CPC-group at UofA and equipped myself with all the excellent tools, I have decided to return to my beloved motherland and dedicate myself in teaching the contemporary technological know-how to the students of BUET and help my country to prosper in the industrial sector. I will be working as a faculty in the Department of Chemical Engineering of BUET from January 2007. I can be reached at shoukat@che.buet.ac.bd or shoukat89@gmail.com.

Research: My research interests include process data analysis, nonlinearity analysis using higher order statistics such as bispectrum and bicoherence, modelling and diagnosis of stiction in control valves, data compression, control-loop performance assessment, monitoring KPIs, equipment health monitoring, root-cause diagnosis of plant-wide oscillations, plant-wide performance assessment. My research includes an innovative mixer of theory and application.
