Our Team

This is an international collaborative project with a consortium of partners from US, UK, Ghana, Kenya and Thailand bringing leading experts from both Engineering and Nutritional science together to develop innovative solutions to address the need of a reliable tool for accurate nutrient intake assessments nutritional studies in low and middle income countries.

Dr Benny Lo, PhD is a Senior Lecturer of the Hamlyn Centre and the Department of Surgery and Cancer, Imperial College London. His research mainly focused on Body Sensor Networks, Wearable Technologies and Computer Vision. Dr Lo is the Principal Investigator of this project, and jointly with Prof Frost, Dr Lo is responsible for the overall coordination and management of the project. Dr Lo oversees the technological development of the project and also leads the engineering research at Imperial College for this project.

Prof Gary Frost, PhD is a Professor of Nutrition and Dietetics at Imperial College and a qualified dietician. He has an interest in understand how new technologies can improve dietary reporting. In this project, jointly with Dr Lo, Prof Frost is responsible for the overall management of the project, and he oversees the technology translation, leads the analysis on the nutrition data analysis, manages the trials of the project, and supervises the field tests.

Prof Kathryn Maitland, PhD is consultant in Paediatric Infectious Diseases at Imperial College and an Honorary Fellow at the MRC Clinical Trials Unit, London but she is based full time in East Africa. Her research largely focused on clinical investigation to gain a better understanding of the pathophysiology of severe malaria and severe malnutrition as well as clinical trials of interventions that may improve outcome. In this project, Prof Maitland leads the trials in Kenya together with Prof Frost.

Prof Mingui Sun, PhD is a Professor of Neurosurgery, Electrical and Computer Engineering, and Bioengineering at the University of Pittsburgh. He has over 20 years of research experience in biomedical sensors, electronics and systems. Prof Sun leads the food preparation research jointly with Dr McCrory, and leads the technological development of the eHat and the associated Artificial Intelligence system.

Dr. Wenyan Jia, PhD is a Research Assistant Professor in the Department of Neurological Surgery at the University of Pittsburgh. Her research interests include biomedical signal and image processing, wearable electronic device and mobile health. In this project, together with Prof Sun, Dr Jia leads the design of eButton/eHat, and software components of the associated Artifiical Intelligence system.

Prof Edward Sazonov,PhD is a Professor of the Department of Electrical and Computer Engineering at the University of Alabama – College of Engineering. Dr Sazonov research mainly focuses on biomedical engineering, embedded systems, signal processing, intelligent systems, and pattern recognition. In this project, Dr Sazonov oversees the development of FoodCam/AIM. Dr Sazonov also leads the hardware development of the project.

Dr Megan A. McCrory, PhD is a Clinical Associate Professor of the College of Health & Rehabilitation Sciences, Boston University. Dr McCrory’s research mainly focuses on understanding the roles of eating patterns, dietary composition and their interaction effects on energy regulation, physiological and psychological factors influencing energy balance, improvement in dietary intake, and physical activity and body composition assessment methods. In this project, Dr McCrory leads the development of training materials and works with personnel at each trial site ensuring validation and standardization of methodology across sites. Dr McCrory also co-leads the assessment and quantification of food preparation and food sources by the device(s) along with co-investigator Prof Sun.

Dr Alex Kojo Anderson, PhD is an Associate Professor of the Department of Foods and Nutrition, College of Family and Consumer Sciences, and an Adjunct Associate Professor of Epidemiology & Biostatistics of the College of Public Health, University of Georgia.  His research focuses on the nutrition of women and infants, infant and young child feeding, breastfeeding promotion and protection, growth of infants and children, body composition of infants, children and pregnant women, as well as community and international interventions for nutrition and health. In this project, Dr. Anderson manages and works closely with the project team  for the development of procedures and implementation of the field research project in Ghana.  He oversee sthe field trials together with Dr. Steiner-Asiedu of the University of Ghana. 

Dr Matilda Steiner-Asiedu, PhD is an Associate Professor of the Department of Nutrition and Food Science, University of Ghana.  Dr. Steiner-Asiedu works closely with Dr Anderson to oversee the field trials in Ghana. She has a very strong presence in communities around Ghana and excellent working relationship with chiefs and elders of the communities. Dr. Steiner-Asiedu has experience with dietary assessment both at the individual and household levels.


Prof Thomas Baranowski, PhD is a Professor of Pediatrics-Nutrition at the Baylor College of Medicine. Prof Baraonowski’s research over the last 30+ years has been directed toward understanding why children eat the foods, and engage in the physical activities they do, as well as designing and evaluating programs, including video games, to help change these dietary and physical activity behaviors to help prevent obesity. In this project, Prof Baranowski acts as an advisor to the Pittsburgh team providing advice on dietary monitoring of mother and children.

Dr Janine A. Higgins, PhD is an Associate Professor of the Department of Pediatrics, Endocrinology Section, at University of Colorado Denver (UCD), and Director of Operations and Nutrition Research Director for the Colorado Clinical Translational Science Institute (CCTSI). In this project, Dr Higgins acts as a consultant advising the Boston team on the dietary data analysis, SOPs, training materials, and guidelines.

Prof Guang-Zhong Yang, PhD FREng CBE is the director and co-founder of the Hamlyn Centre at Imperial College London and is Deputy Chairman of the Institute of Global Health Innovation.  In this project, Prof Yang acts as an advisor for the project providing advice on technology development.

Dr Jindong Liu, PhDis a Hamlyn Research fellow of Imperial College London. His research mainly focuses on human auditory system and bio-inspired robotics for clinical translation. In this project, Dr Liu serves as a technical advisor to the Imperial Team supporting the development of the ear-worn food intake sensor.

Dr Surapa Thiemjarus, PhD is a researcher from the National Electronics and Computer Technology Center (NECTEC) Thailand.
