Dr. Mahmmod is an enthusiastic veterinarian, lecturer, and results-oriented researcher. With a career spanning 20 years in clinical practice and academic pursuits, Dr. Mahmmod holds a Ph.D. on cattle health and epidemiology from University of Copenhagen, Denmark. His Ph.D. studies focused on udder health management and mastitis epidemiology in dairy cows. He pursued his postdoctoral fellow training at University of Minnesota, USA. He worked on different dairy production medicine topics, particularly bovine lameness, and herd health management in organic dairy farms in the Midwest. In 2016, he joined University of Copenhagen as a postdoctoral fellow after being awarded an international fellowship “Merit Postdoc Fellowship”. He investigated the epidemiology and diagnostics of contagious mastitis pathogens in dairy herds using Bayesian latent class modelling. In 2018, he joined Animal Health Research Centre (CReSA) at Autonomous University of Barcelona, Spain after receiving the European Marie Skłodowska-Curie Fellowship. He worked on metagenomics characterization of microbial communities, animal microbiome, and their interaction with animal health and production. Dr. Mahmmod obtained his DVM followed by a combined internal medicine residency and Master program at Zagazig University. He studied the clinical epidemiology of ticks and tick-borne diseases in cattle and buffaloes in Egypt. Through his academic carrier, he was a recipient of several awards and recognitions, and his research work has been listed as Editor’s Choice in the journal of Dairy Science. For instance, he received the European Marie Skłodowska-Curie Fellowship, Medal of Excellence from the President of Egypt, best master thesis in veterinary sciences, and State Encouragement Award, etc.).
Before joining the LIU College of Veterinary Medicine as an Associate professor, Dr. Mahmmod had been promoted into several academic positions at research institutions in Denmark, Spain, the USA, China, Egypt, and UAE, starting from an instructor/ demonstrator position in farm animal medicine and epidemiology. Dr. Mahmmod is a Fellow of the Higher Education Academy and a certified expert in digital teaching and learning from Blackboard Academy. He served as a system course team leader and coordinator of many veterinary core courses including veterinary professional practice, veterinary epidemiology, infectious diseases, animal nutrition, animal welfare and animal science. At the international level, Dr. Mahmmod is serving as an expert on the Quadripartite Technical Group on the Economics of AMR (QTG-EA), the WHO, in addition to the United Nations Emergency Management Centre, the FAO. He has supervised many trainees including master, PhD. He has been the recipient of many prestigious grants from various national and international funding agencies. Dr. Mahmmod has published more than 80 manuscripts in top ranked peer-reviewed journals. He is an Ad hoc reviewer and serves on the editorial board of many journals in the field (Frontiers of Vet Sciences, JDS, Animal, PREVET, BMC veterinary research, etc.). He is also a grant reviewer for many funding bodies in the Middle East and Europe (e.g., ASRT, STDF, COST). He is a member of many professional scientific societies such as ARPAS, EAAP, NMC, ACE, AAFSPHV, European Cattle network, and Mastitis Research Workers Network.
Dr. Mahmmod has a good teaching experience while adopting Bloom's Taxonomy concept in his courses. His teaching style is student-centered, primarily research-oriented teaching. He has developed syllabi and directed courses mainly in livestock production medicine, food animal health, and production. During his interactions with students, Dr. Mahmmod strives to convey his passion for the discipline and to promote a learning environment that fosters student engagement and small group discussion. He encourages cultivating and refining the critical thinking, communication, and methodological skills necessary for future veterinarians to succeed in their research and careers so that they could then go on to improve animal welfare, protect humans against zoonotic diseases, and subsequently make our world better.
