My current research is centered on developing innovative and sustainable processes for the production and complete valorization of microalgal and microbial biomass within an integrated biorefinery framework. My group, the Multi-Way Bio-Focussed Engineering Research group, is pursuing this through three main interconnected thrusts:

Advanced Photobioreactor Design and Optimization: A primary focus is the development and hydrodynamic characterization of novel, energy-efficient photobioreactors. We are particularly investigating thin-layer, wavy-bottomed cascade systems. Our goal is to enhance mass transfer and optimize light utilization by creating hydrodynamically-induced "flashing light" regimes, which can significantly boost photosynthetic efficiency and biomass productivity.

Multi-Scale Modeling for Industrial Application: We employ and validate CFD models to simulate the complex interplay of fluid dynamics, mass transfer, and light exposure within photobioreactors. This modeling work is crucial for optimizing reactor geometry and operating conditions, and for developing reliable scale-up methodologies to transition promising lab-scale concepts to robust industrial-scale operations.

Green Chemistry for Integrated Biorefining: My research actively explores the application of novel, environmentally benign solvents to design efficient "one-pot" extraction and fractionation processes. We are investigating switchable-hydrophilicity solvents (SHS) and supercritical fluids to selectively recover a cascade of valuable products—such as lipids for biofuels, pigments like astaxanthin, and proteins for food/feed applications—from wet biomass, thereby reducing the energy footprint and simplifying the overall downstream process. This work is closely linked to creating circular economy models by integrating microalgal cultivation with the treatment and valorization of agro-industrial wastewaters.
