Upcoming Instructors

  • Samuel Bajomo


  • Senior Heat Transfer Specialist, Engineering Services, completed his BEng, MSc in Mechanical Engineering at University College London, London, United Kingdom (UK), majoring in Materials Science and Structural Mechanics. He began his career with MW Kellogg working on mechanical design of pressure vessels and heat exchangers and later transitioned into the heat transfer group as Principal Heat Transfer Engineer. In 2012 he moved to Wood Plc, London, UK where he oversaw the thermal and mechanical design of heat exchangers and fired equipment for several major oil and gas and petrochemical projects. His experience spans front-end engineering design (FEED), requisition, detailed engineering, and oversight of equipment manufacture. Bajomo then operated as an independent heat transfer consultant, working with equipment manufacturers and end-users on a wide variety of troubleshooting and design verification projects. His exchanger design and practical industry experience brings a uniquely qualified contractor’s perspective to HTRI’s Engineering Services team. Bajomo also currently serves on the board of the Institution of Mechanical Engineers (IMechE), Pressure Systems Group, and is a CEng MIMechE.

  • Aovi Deshpande


  • Research Engineer, Engineering Services, earned a BS in chemical engineering from the University of Mumbai, India. After working as a process engineer at KBR Inc. in India, Deshpande completed an MS in chemical engineering from Texas A&M University in College Station, Texas, USA. At HTRI, she provides end-user technical support and consulting services to members, ensuring that software methods reflect actual user experiences. She also performs contract thermal rating and design reviews, as well as works to execute assigned HTRI research projects related to process heat transfer for software enhancements.

  • Sean Hennigan


  • Principal Engineer, Engineering Services, holds BEng and MEng degrees in Chemical Engineering from the University of Bradford (UK), including internships in France from 1988 – 1990. He has spent 33 years at the Saltend chemicals manufacturing site in Hull, working first for BP Chemicals and since 2021 for INEOS Acetyls. His global support work spans modeling, analysis, design, operations, turnarounds, commissioning, troubleshooting, technology development, intellectual property, and training. In 2008 he became BP Chemicals’ Separations and Heat Transfer Advisor, specializing in ASPEN simulation and Xchanger Suite®, delivering thermal design and troubleshooting for hundreds of heat transfer applications. At INEOS, his role expanded to Process Engineering Advisor, adding CFD and reliability analysis. He joined HTRI in 2026. Hennigan has been a chartered engineer since 1998 and an IChemE Fellow since 2015.

  • Stefano Tagliaferri


  • Engineer, Research, completed his MS in Petroleum Engineering from the Technical University of Denmark, Copenhagen, in 2017. During his studies, he served as a research assistant at the Danish Hydrocarbon Research and Technology Center, designing and conducting high pressure and high temperature core flooding experiments to replicate oil extraction in North Sea Fields. Prior to joining HTRI, Tagliaferri worked as an R&D Engineer at Filtration Technology Corporation in Houston, Texas. In this role, he developed and executed coalescer test stands for liquid-liquid separation and conducted bench and pilot test scale testing for various fluid contaminant separation applications. At HTRI, Tagliaferri is involved in studying and testing coatings for heat exchanger applications, as well as in research related to non-Newtonian fluids and crude oil fouling.
