Research Interests

Decision analysis for improving transparency and stakeholder engagement in fisheries: Project goals are to incorporate fisher knowledge and economic and social considerations into fisheries decision models.

Stock assessment for recreational fisheries: Working on a growth type group stock assessment model for Rainbow trout fisheries in B.C. stocked lakes.

Bayesian Hierarchical modelling: Worked on a model to understand influence of landscape characteristics and stocking strategies on fish growth in B.C. stocked lakes recreational fisheries.

Decision analysis: Stock-Optim developed using Bayesian Belief Network software performs decision analysis for stocking strategies for B.C. small lakes fisheries. The model integrates findings from empirical published work on population dynamics and fisheries with survey information on angler typology.

Ecosystem modelling: I have contributed to developing ecosystem models for Raja Ampat (Eastern Indonesia), Mille Lacs Lake (Minnesota), and Haida Gwaii (British Columbia) ecosystems.

Semi-quantitative analyses: Rapfish (for rapid assessment of fisheries status) is a multidimensional scaling approach applied to scores of fisheries for various ecological, fisheries, economic, and social sustainability attributes.


I did my PhD on marine ecosystem restoration and ecosystem-based management with Prof. Tony Pitcher at Fisheries Centre, University of British Columbia (UBC). Prior to that I did my masters in fisheries resource management from Central Institute of Fisheries Education, Mumbai. My fascination for fisheries management comes from the time spent in landing centres in Kochi and Mumbai and opportunities to interact with fishers during internship towards my Bachelor degree in fisheries science from Kerala University of Fisheries and Ocean Studies, Panangad, Kochi.
