(6la) Process Systems Engineering (PSE)

Authors 

Singh, R. - Presenter, Rutgers, The State University of New Jer
Abstract: My main research focus is process systems engineering (PSE) and current application domain is continuous pharmaceutical and bio-pharmaceutical manufacturing. However, the PSE methods and tools that I developed are generic and can be applied to any manufacturing industries. Currently, pharmaceutical and bio-pharmaceutical industries are going through paradigm shift from conventional batch to continuous manufacturing process in which PSE can play a very significant role. Furthermore, there is a need of advanced modular continuous manufacturing platform technology for fast and robust development of pharmaceutical and bio-pharmaceutical products. Master formulations, process models, standardized sensing and control architecture, superior automation and novel methods and tools need to be developed to enable platform technology. This area of research and education are highly encouraged and supported by pharmaceutical and biopharmaceutical companies, academic institutions, regulatory authority (FDA) and national science foundation (NSF).

In this work, a scientific foundation for the optimal design, optimization and control of the modular continuous process involving structured organic particulate systems has been developed. The mathematical models for continuous manufacturing of active pharmaceutical ingredients and final product tablet, has been developed for virtual experimentation and applied for plant design, optimization and control. The developed continuous tablet manufacturing plant and process model has been adapted by several pharmaceutical companies. A flexible monitoring and control system incorporating different PAT techniques and tools and control strategies for continuous pharmaceutical manufacturing process has been designed and implemented to Rutgers pilot-plant. Different control strategies such as PID, PID coupled with dead time compensator, and MPC has been compared and evaluated practically for pharmaceutical process control. A new hybrid MPC-PID control strategy has been developed and implemented into the pharmaceutical tablet manufacturing plant and its performance has been found better than the other control strategies. A novel RTD based control system has been developed and implemented into the pilot-plant. Novel sensing methods have been developed for real time measurements of powder density and powder level. Feedforward control system has been integrated with feedback control system to take proactive mitigation actions on raw materials and process variability. A moving horizon based Dynamic Real Time Optimization (MH-DRTO) method has been also developed to provides the optimal operational set points for the control system. The developed control architecture has been implemented into pilot-plant.

Biosketch: I am working as an Assistant Research Professor at C-SOPS, Department of Chemical and Biochemical Engineering, Rutgers University, NJ, USA. I am the recipient of prestigious EFCE Excellence Award given in Recognition of an Outstanding PhD Thesis, from European Federation of Chemical Engineering. I received several grants as a PI/Co-PI and have well stablished research group. I have published more than 63 scientific research papers, written 12 book chapters, presented at over 100 international conferences and edited one pharmaceutical book published by Elsevier. I am actively serving as a conference session chair, Journal reviewer and guest editor.

Research Interests: Process Systems Engineering (PSE) including process control, process modelling and simulation, process optimization, machine learning, process monitoring and PAT, data science, cyber infrastructure, cyber-physical security, new methodology and software development. Continuous pharmaceutical and biopharmaceutical manufacturing.

Teaching Interests: My teaching experience that I acquired serving as a teaching assistant, and lecturer (assistant professor), makes me confidant to develop and teach any courses of chemical and biochemical engineering. The industrial invited crash courses that I have given provide me opportunity to extend my teaching skills to cover more applied courses and to interact with highly experienced scientist and operators from manufacturing companies. I demonstrated my skills to instruct hands-on exercise through several workshops that I conducted. Several training courses that I conducted for industrial and academic participants make me instrumented with additional capability of building highly skilled workforce. I developed online course modules for FDA where I learn how to develop and give online courses. I am open to teach any courses that your university will assign me. If needed, then I can develop new courses based on my research outcomes.
