Professor Ramesh Kumar's research lab specializes in sustainable chemical processes and environmental remediation, with a strong focus on membrane technology for wastewater treatment and green biodiesel production. The lab investigates advanced separation techniques using nanofiltration and microfiltration membranes to remove toxic contaminants such as cyanide and phenol from industrial effluents. Additionally, the lab explores the molecular mechanisms of carcinogenesis, particularly the role of ras oncogenes in early tumorigenesis, using animal models. The integration of membrane-based technologies with green chemistry principles underpins the lab’s mission to develop efficient, eco-friendly solutions for industrial and biomedical challenges.

The identification of ras oncogenes in human and animal cancers including precancerous lesions indicates that these genes participate in the early stages of neoplastic development. Yet, these observations do not define the timing of ras oncogene activation in the multistep process of carcinogenesis. To ascertain the timing of ras oncogene activation, an animal model system was devised that involves the induction of mammary carcinomas in rats exposed at birth to the carcinogen nitrosomethylurea.
Investigations on separation of cyanide from coke wastewater were carried out in a cross flow nanofiltration membrane module following microfiltration of real industrial wastewater. Different composite polyamide nanofiltration membranes were used in the system while studying their effectiveness in cyanide separation under different operating conditions. Transmembrane pressure, pH, and cross flow velocity exhibited strong influence on percentage removal of cyanide. 94% cyanide rejection with a pe
