Nadia Moran Garcia, PhD; Postdoctoral Research Fellow

I completed my PhD in Molecular Biomedicine in the Center of Investigation and Advanced Studies of the National Polytechnic Institute (CINVESTAV-IPN) in Mexico City in 2018. While my PhD studies focused on the development and characterization of diarrheagenic, infectious disease models and my academic background is in chemistry, pharmaceutics and biology, I have had a strong interest in the interdisciplinary field of nutrition since my undergraduate studies. I gained my first research experience as part of my social service and undergraduate thesis project on an animal study investigating the effects of maternal protein restriction during gestation and breastfeeding on offspring development at the National Institute of Nutrition “Salvador Zubiran” (INNSZ) in Mexico City. For my Master thesis research that I conducted at the CINVESTAV-IPN, I worked on the effect of combined vitamin A and zinc supplementation in children on the prevalence of diarrheagenic E. coli groups, that are important etiological agents of pediatric diarrhea.

I joined Dr. Lamers’ research team as a postdoctoral fellow in April 2018 to work on the transnational and multidisciplinary project DERiVE for the DEvelopment of Riboflavin biomarkers to relate dietary sources with status, gene-nutrient Interactions and Validated health Effects in adult cohorts.


Larissa Rossen, PhD; Postdoctoral Research Fellow

I received my PhD from the University of New South Wales, Australia, investigating early predictors of childhood development in the first year of life as part of the Triple B study (Bumps, Babies, and Beyond), a longitudinal birth cohort study which examines a wide range of biopsychosocial factors that relate to the health and development of Australian children.

My post-doctoral research on an Australian population-based data linkage study of child mental health and wellbeing in a cohort of children (n=87,000; the NSW Child Development Study) investigated patterns of early childhood resilience and vulnerability for later mental health, education, work, and other outcomes.

I continue to remain passionate about understanding and intervening around early risk and protective factors for children’s health and development. I joined the Lamers Lab in June 2019, and my research focuses on nutrient status, feeding patterns, and neurocognitive development in toddlers.

Simaran Kalkat, BSc; Medical Student in Clerkship

I am currently studying medicine at UBC (MD Class of 2020) and am additionally interested in nutrition. Specifically, my interests lie in food security and access as well as optimal nutrition for general health and in states of disease. I currently have my BSc in Biochemistry from UBC, and I have a passion for food, yoga, running and traveling.

The current focus of my research is vitamin B12 status in South Asian pregnant women, as this population is particularly vulnerable to lower B12 status during pregnancy. Vitamin B12 is important for appropriate fetal growth and development, contributing to neural tube closure, and future cognitive development and cardiometabolic health of the child. Nutrition is a complex and evolving topic, and I am excited to not only contribute to this field of knowledge but also use it as a tool for my future practice.

Angella Lee; Undergraduate Summer Student

While I am an international student majoring in Human Biology, Health and Society at Cornell University, Vancouver is my hometown. At Cornell, I am a member of the Gu Lab, where I investigate the effect of nutrient intake on mitochondrial function at a molecular level. When I learned that mitochondria are not only exclusively transferred to infants by their mothers but also implicated in cognitive failure, I became interested in pediatric nutrition as a form of preventive healthcare. Thus, I joined the Lamers Lab in 2020 to explore the importance of adequate nutrition in early life for cognitive development. Currently, as an undergraduate student in the BC Children’s Hospital Summer Student Research Program, I am involved in the toddler nutrition study.

Graduate Students and Postdoctoral Fellows


Maria Fernanda Mujica-Coopman, PhD

My interest in human nutrition research started during my undergraduate studies. I completed my MSc in Human Nutrition at the Institute of Nutrition and Food Technology (INTA), University of Chile, in 2015. The main focus of my master thesis was the comparison of iron and zinc supplementation on anemia in Chilean childbearing-aged women. As part of a Canada-Chile Leadership Exchange Scholarship, awarded 2014, I participated in a collaborative project between Drs Yvonne Lamers and Gilberto Kac (Rio de Janeiro Federal University, Brazil). In this project, we studied the physiological changes of vitamin B6 status in Brazilian pregnant women from a prospective cohort study conducted by Dr. Kac.

Since then, my research interest has focused on maternal B-vitamin status and early development. My PhD research aimed to assess the role of the methyl nutrients folate, vitamin B-6, riboflavin, choline and betaine in relation to epigenetic programming for fetal growth and obesity related genes. I am also interested in exploring the role of maternal methyl nutrient status on anthropometric birth outcomes such as birth weight and adiposity.

Awards received: UBC Four-Year Doctoral Fellowship (4YF), Canada-Chile Leadership Exchange Scholarship, Latin American Society for Nutrition (SLAN) Leadership Award


Larisse Melo, MSc

I graduated from the Federal University of Rio Grande do Norte (UFRN – Natal, Brazil) with a Bachelor’s degree in Dietetics. During my undergraduate studies, I worked for 4 years as an undergraduate research assistant assessing vitamins A and E status in the maternal-child population. That was the first step towards my primary goal, which is building a career in academic research.

I completed my MSc in Human Nutrition at UBC in 2019 under the supervision of Dr. Lamers. My Master’s project aimed to develop and test novel food products fortified with B-vitamins to help reduce the prevalence of vitamin inadequacies in Canadians. During my MSc at UBC, I also led a small project on the breast milk vitamin B12 concentration of Indonesian mothers in a resource-poor setting, in collaboration with Dr Lisa Houghton, University of Otago.

Chia-Ling (Jennifer) Ho, MSc

My research focused on vitamin B-6 adequacy in healthy women. Vitamin B-6 is an essential nutrient important for blood cell formation, energy metabolism, and brain function. In my MSc projects, I determined vitamin B-6 status in young and older adult women in Metro Vancouver with the overall goal to contribute new knowledge on vitamin B-6 in Canada by characterizing women at-risk for vitamin B-6 deficiency. My research outcomes provide new information for public health measures and future research trials since there are few data about vitamin B-6 status in Canadians.

My background is in Nutrition. I finished my undergraduate education in Taiwan at Taipei Medical University. During my undergraduate studies, I worked in a research laboratory and contributed to investigations on chemoprevention of rice bran in colon carcinogenesis in rats.

Awards received: Indrajit and Manjula DESAI Prize in Human Nutrition


Mohammad Saroar Zubair, MSc

As a master’s student in Human Nutrition at UBC, my academic interests lied in exploring micronutrient status associated with health and wellbeing of vulnerable population groups in Canada. The focus of my research was the description of riboflavin status and its association with vitamin B6 status in older adult women.

Previously, I have studied Nutrition and Food Science at the University of Dhaka, Bangladesh and worked for BRAC (NGO) in Nutrition Intervention and Home Fortification programs. I am a travel enthusiast and I am currently enjoying the diversity of cultures and food, which Vancouver has to offer. I see myself as a development professional in the future and want to build on my graduate research’s practical implications through my work with marginalized communities around the world.


Amy McMahon, PhD; Postdoctoral Research Fellow

I completed my PhD in Human Nutrition at the Northern Ireland Centre for Food and Health (NICHE) at Ulster University, Northern Ireland, in 2017. My PhD focused mainly on investigating the underlying mechanisms behind the blood pressure lowering effects of riboflavin, in individuals with a genetic predisposition to elevated blood pressure. This is where my interest in B-vitamins, public health and nutritional biochemistry began. During my PhD, I gained extensive experience in nutritional epigenetics and the design and conduct of human intervention studies.

My research encompassed various projects in nutritional biochemistry with a special focus on understanding the metabolic consequences of inadequate B-vitamin intake in young adult women.

Theresa Schroder

Theresa Schroder, PhD 

The main focus of my research was on the assessment, prevalence and effects of maternal and infant vitamin B12 deficiency. We developed a simple and precise method to determine methylmalonic acid, a functional indicator of vitamin B12 status, in dried blood spots. This has allowed for minimally invasive assessment of functional vitamin B12 status. We are interested in applying this method as a second tier-test to identify newborns at risk for vitamin B12 deficiency. We have further pursued studies to determine vitamin B12 status of mothers and their infants in resource-poor settings using dried blood spots, in collaboration with Dr Lisa Houghton at the University of Otago. As vitamin B12 is crucial for a healthy fetal and infant development, the overall goal of my research is to contribute to the public health goal of nutritional adequacy of pregnant women and their babies by early identification of potential vitamin B12 deficiencies.

My background is in analytical chemistry and nutritional biochemistry. I have transitioned to Human Nutrition from an undergraduate degree (Vordiplom) in Chemistry and a Master’s equivalent degree (Diplom) in Food Chemistry from Germany. My previous experience lies within nutrient analysis of foods and bioavailability studies. My motivation is to combine my analytical knowledge with my interest in human biochemistry to contribute to health-relevant identification of potential nutrient deficiencies in Canada and worldwide. In my free time, I like to explore the beauty of BC’s nature by going hiking, biking, or skiing and taking my van camping.

Teo Quay, MSc

My research addressed questions around vitamin B12 status in reproductive-aged women of South Asian and European ethnicity. Vitamin B12 adequacy is critical during early pregnancy in the periconceptional period. With an estimated 40% prevalence of unplanned pregnancies, it is essential for young adult women to maintain vitamin B12 adequacy throughout reproductive years.

With my research outcomes, we determined the prevalence and predictors of vitamin B12 status in South Asian and European young adult women in Metro Vancouver, investigated  biomarker discrepancies in the classification of vitamin B12 deficiency, and applied novel biomarkers in the assessment of vitamin B12 status.

Through this research experience and related community engagement, the challenges in recruitment of ethnic minorities became apparent leading me to conduct and publish a scoping review on the barriers and facilitators to recruitment of South Asians to health research.
