My recent and current research interests comprise various topics of Environmental Fluid Mechanics with particular focus on:

• Turbulence in open-channels, rivers, estuaries, and coastal areas
• Benthic boundary layers, water-sediment interfaces, and sediment transport (cohesive/non-cohesive), including sand wave dynamics, turbulence-sediment interactions, erosion, re-suspension, flocculation, and bed particle dispersion
• Flow-biota interactions and transport processes (periphyton, moss, mussels, macrophytes, invertebrates, fish)
• Hydraulic resistance and channel stability in gravel-bed and sand-bed rivers
• Overland flow hydrodynamics and soil erosion
• Hydraulic instrumentation and measurement techniques
• Channel networks, meandering and braided channels, granular surfaces, and Mars topography

Currently I am working on development of a broad multidisciplinary research programme focusing on fluvial hydraulics (sediment transport, turbulence, flow resistance, mixing), eco-hydraulics (flow-biota interactions at multiple scales, ecologically relevant transport processes, vegetated channels, surface-subsurface flow interactions, benthic boundary layers), and fundamental issues of rough-bed flow hydrodynamics.
