Research Interests

Ecohydrology of Freshwater Ecosystems, Watershed Hydrology, Hydrological Modelling, Climate Change Impacts, Stream Ecology 

I am interested in understanding water driven changes in ecosystem response in freshwater systems. To achieve this, I use field, lab as well as computer-aided simulations that assist me in testing hypotheses related to impacts of external stressors, such as climate change, floods and droughts on biota of freshwater streams. I use an interdisciplinary approach that integrates field hydrology, biomonitoring frameworks, and distributed modeling to understand the coupling between flow regimes, sediment sources, and biological communities. My ultimate goal is to develop predictive ecohydrological frameworks that inform water resource management and biodiversity conservation under a changing climate.

I am particularly interested in questions such as:

How do flow intermittency and droughts influence river resilience of benthic macroinvertebrates? 

How sensitive are various hydrologic and environmental gradients on sediment and nutrient transport towards shaping community composition? 

How can integrated models linking hydrology and biodiversity help predict ecological responses to altered climate and land use? 

How to improve our understanding of critical source areas and their representation in distributed hydrological models?

By combining hydrologic and ecological models (e.g., SWAT, CASiMir) with state of the art biogenomic approaches with we aim to uncover how hydrologic connectivity and landscape processes regulate species distributions and ecosystem functionality.
