Email: simtiaz@ualberta.ca Location of work: Chemical and Materials Engineering Building (Room 270)- University of Alberta Personal Details: I was born in Bangladesh some time ago. I spent my childhood in a small town and a large part in close contact with nature in the tea gardens. Still today tea gardens are the most fascinating place to me. From my 7th grade to 12th grade I studied in a residential school (Faujdarhat Cadet College, http://www.ofana.org/), these have the same structure as the public schools of UK. Though strict discipline was implemented in the school we found way around to make life enjoyable. Some examples would be stealing coconut from the nearby staff quarters in the midst of the night or catching fish from the ditch with mosquito net. These activities may sound silly now, but these kept us going through the otherwise very tough life. I did my Bachelors in Chemical Engineering from Bagladesh University of Engineering and Technology (BUET, http://www.buet.ac.bd/) in 1997 securing the first position in the class. Soon after that I joined the same department as a lecturer. As a lecturer I was a co-instructor with senior professors for several courses including, unit operations, fluid mechanics, and materials and energy balance. I conducted many experiments in the heat transfer, mass transfer, fluid mechanics and unit operations laboratories. In September, 1999 I moved to Canada to do my Masters in Chemical Engineering from University of Calgary. My specialization was in Environmental Engineering. I did my thesis under supervision of Dr. Hamid R. Baheri and the title of my thesis is "Modeling the Fate of Pollutants in Small Water Bodies using Tracer Information". This has implementation in estimation of the volatile component from water bodies like waste water treatment plant and mining areas like tailings pond. Research: In January 2002 I started my journey for PhD at University of Alberta, and to the surprise of many in a completely different field from my Masters, in the area of Process Control. My PhD supervisor is Prof. Sirish L. Shah. My area of research is treatment of missing data in data based analysis. In many data based analysis often in the presence of missing values the residual terms are neglected. This has caught my attention. To solve this problem I have extended Principal Component Analysis (PCA), Iterative PCA and Maximum Likelihood Factor Analysis (MLFA) in the Data Augmentation framework for dealing with missing data. I have also shown the novel application of missing data handling techniques in building model from compressed data and uneven length batch process data. All currently used methods use univariate methods for reconstruction. The proposed missing data handling technique based method deals with this problem in a multivariate frame work. Therefore it is better in preserving the original correlation of the data. This is illustrated using a dataset from a refinery where the original data was compressed using swinging door compression algorithm and subsequently reconstructed using the traditional linear interpolation method and the proposed missing data handling technique. |
