Karina Cirone

Laboratory Manager

Faculty of Veterinary Medicine, University of Calgary

I am from Balcarce, Argentina. I completed a B. Sc. in of Food Science and Technology at the University of Mar del Plata, Argentina. Thereafter, I completed a Dr. degree in Animal Science at the University of of Buenos Aires province (Argentina) investigating diseases in cattle caused by mycobacteria. Currently, I am a Research Scientist at the National Institute for Agricultural Technology (Argentina), and Assistant Professor in General Microbiology and Food Microbiology at the Faculty of Agricultural Sciences (University of Mar del Plata, Argentina). There, I have worked on research projects focusing on cattle diseases caused by zoonotic bacteria and protozoan parasites. I joined Dr. Cobo’s lab in March 2022 to acquiring training in immunology and molecular biology. My current research investigates the gut innate immunity in infectious colitis exploring models of colitis in calves, pigs, and mice and role of bioactives in bovine colostrum on gut health.

Priyoshi Lahiri

I was drawn to the paradigm of the drug-body interaction, when I first learned about the hypothesis of ‘magic bullet’ that can course through our body and find and bind to its target with exquisite specificity, thereby transforming a previously fatal and lethal disease to a treatable one. Being evoked with keen interest to delve into the depth of this science, I pursued a degree in Bachelors of Pharmacy and graduated summa cum laude from my native country, Bangladesh. This was a turning point in my academic life as it started to instill in me an unbounded fascination about the immune systems of living organisms and propelled me to immerse myself in the world of biological molecules that function with incredible intricacy to maintain and perpetuate life. Thus in an urge to comprehensively understand the basics of the immune system, I completed a course-based one-year Master’s Degree in Integrated Immunology at the University of Oxford in 2016 and then worked as a research assistant there for a period of 6 months. I joined Dr.Cobo’s lab in September 2017 with the conviction of acquiring extensive training in molecular biology and immunology under his supervision. My primary research focus now is studying the immune-modulatory roles of cathelicidins against Treponema infections in mice as model organisms.

Ph.D. Microbiology and Infectious Diseases Graduate Program, Cumming School of Medicine, University of Calgary 

I was born in Kandy, Sri Lanka. I received my Bachelor’s degree in Agriculture (Specialized in Animal Science) from University of Peradeniya, Sri Lanka (2012). Upon graduation, I joined the Department of Animal Science, Faculty of Agriculture at my alma mater, as a Temporary Lecturer (2012-2014). Then, I was awarded a Master’s degree in Preventive Veterinary Medicine at Chungnam National University, Daejeon, Republic of Korea, supported by the Korean Government Scholarship Program (2014-2017). There, I studied the antimicrobial and immunomodulatory properties of chitosan derived nanoparticles and their effects on gut microbiome using the zebra fish model. I joined Dr. Cobo’s lab (2020) for my PhD, where I am investigating the immunomodulatory role of cathelicidins regulating Tollip and Reg in intestinal defences.


MS.c. Microbiology and Infectious Diseases Graduate Program, Cumming School of Medicine, University of Calgary 

I completed my Bachelor of Health Sciences degree at the University of Calgary in the summer of 2019. Throughout my degree, I was actively involved in various research projects pertaining to wound healing and skin regeneration in the Biernaskie Lab. During the last year of my degree, I completed my honours thesis, which consisted of exploring the role of HIC1 in skin regeneration in vivo. My undergraduate research experience inspired me to pursue a graduate degree and has led me to join the Cobo Lab in January 2021. My current research investigates the effect of cathelicidin on neutrophil activity during infectious colitis.
