Academic and Professional Appointments
- Geog 345 (Interpretation of aerial photographs): As Instructor I am teaching Geog 345 for three semesters now (Fall 2008, Spring 2009, Spring 2010). The class capacity is 25 and in average I have 20 students in the class. This course introduces the basics of aerial photography including radiant energy, properties of the photographic image, photo-geometry, photogrammetric measurement, photo acquisition, and interpretation of aerial photographs. Emphasis is placed on practical training in an effort to make the student a competent user of air photos for a variety of geographic and multidisciplinary applications.
- Geog 103 (Introduction to Geography): I have taught Geog 103 in Summer 1, 2009. The class capacity was 30 and I have 19 students in the class. This course introduces students to the breadth and excitement of the field of geography and illustrates the earth science, culture-environment, location and area analysis traditions of geographic research and writing. It also explores the various sub-fields of geographic inquiry and shows how geographic expertise can be used in important decision-making and problem solving contexts.
Research Assistant:
I have worked as research assistant from Summer 2006 to Summer 2007 for the NSF funded project “Tracking Hydraulic Sediment in Sacramento Valley, California” under PI Dr. Allan James. This is also my PhD project The project involves with detecting, measuring and monitoring hydrological responses of a natural system and sediment analysis using both remote sensing techniques and field study, thereby analyzing morphometry and migration of channel network and sediment erosion. It also involves LiDAR data cleaning, analysis and interpretation, Aerial photo and historical map registration and analysis to create the data for time series analysis, Soft-copy photogrammetric analysis to create DEMs from stereo photos, morphometry analysis of surface water system and sediment budget analysis.
Teaching Assistant:
- Geog 551 (Principles of Remote Sensing): I worked as teaching and lab assistant to Dr. John R Jensen for Geog 551 in Fall 2009. This course introduces the basics as well as the advance principles of remote sensing. My responsibility was to supervise the laboratories associated with each class and also to give occasional lectures.
- Geog 201 (Landform Geography): I worked as teaching and lab assistant to Dr. Allan James for Geog 201 in Fall 2007. This introductory course explores the diverse types and formation processes of landforms and LULC classification. My responsibility was to supervise the laboratories associated with each class and also to give occasional lectures.
- Geol 103 (Environment of Earth): I worked as teaching and lab assistant to Dr. Venkat Lakshmi for Geol 103 in Spring 2006. This course introduces the basic concept of environment studies and principles of different geological processes. My responsibility was to supervise the laboratories associated with each class and also to give occasional lectures.
Department of IT and GIS, Richland County Government, South Carolina
GIS Intern:
In Summer 2008 and 2009, I worked as summer intern in Richland County geographic information division. Here I developed, implemented and deployed a LULC classification algorithm on object based digital image classification for the classification of high resolution 4- band digital aerial photographs for Richland County South Carolina, using Definiens Developer(Ecognition) Software.
Presidency College, Kolkata, India
Lecturer:
I worked here as Lecturer from January, 2004 to December 2005. I offered courses on basic Remote Sensing and GIS and Geomorphology ( Total students-74) in Post Graduate Department of Geography
Effluent Water Treatment Corporation:
GIS analyst:
I worked here from January 2003 to December 2003. My basic responsibility in that organization was to digitize tube wells and add ground water data as attributes. After that I used to interpolate a surface from the groundwater level data and thereby predicted the flow rate and direction for the ground water in the region. This project also had a byproduct of detecting arsenic affected zones and thereby quarantined those zones from drinking water resources.
