About Larissa J Strath

My research is largely focused on the effects that dietary composition has on the modulation of the pain experi ence, specifically through epigenetic and immune mechanisms. With that in mind, I have dealt with a variety of painful conditions and pathologies ( i.e. chronic low back pain, knee osteoarthritis, fibromyalgia etc.) and understanding of nutrient status and their effects on the system at a variety of ages (i.e. inflammation and oxidative stress). My areas of expertise include nutritional biochemistry, pain medicine, neuroscience, and epigenetics. My experience cross es borders, having basic science, clinical science, and epidemiological opportunities over the course of my doctoral training. My PhD work employed the use of nutritive model s to identify factors that may contribute substantially to the development and per petuation of chronic pain , with an emphasis on sex, gender and racial disparities therein . I have extensive experimental skills in the acquisition, protocol design and execution, and analyses of a variety of nutrition – based models (i.e. diet pattern analy sis, nutrient analysis, Dietary Inflammatory Index) in humans and rodents. I have advanced theoretical and practical skills in designing , i mplementing and analyzing various neuroscience – based pain – related measures. My doctoral training gave me extensive e xperience in the use of dynamic quantitative sensory testing, as well as experience investigating blood – based inflammatory and oxidative stress mediators and standardized measures of psychosocial assessment. Over my career, I have used several statistical methods including multivariate regressions, modified Poisson regressions, analysis of variance (ANOVA), as well as mediation and moderation analyses to understand these data. My dissertation work has resulted in the publication of 4

first – author, experime nt – based manuscripts, 4 first author review articles, and 1 collaborative manuscript related to HIV and chronic pain. My current research interests center around understanding the nutriepigenomic mechanisms that contribute to the pain experience observed i n various types of acute and chronic pain. Additionally, my future research interests include how the nutriepigenomic/pain relationship impacts cognition and the development of neurological diseases such as Alzheimer’s Disease over time. At the Universit y of Florida (UF) , Dr. Cruz – Almeida ’s mentorship has afforded me a unique opportunity to employ my research skills related to nutri – biological and psycho social pain phenotyping in a an aging population and to expand the existing body of literature specific to epigenetic and neuroscientific pain – related mechanisms

Teaching Philosophy
My teaching philosophy rests on three primary objectives. First, I want my students to learn the fundamental content of the course I am teaching. Second, I believe in orienting students to both the science and application of a discipline. Within the biom edical field, a disconnect often exists between professionals who primarily conduct research and those who primarily provide patient care. Providing students with a scientific perspective (i.e., research, theory), as well as the application perspective (i .e., how can this information be used in the real world) of the content of the course is an important step in bridging this gap. Furthermore, I believe is important for doctoral – level students to develop an appreciation and understanding of both pre – clinic al and clinical research and the importance of continuous cross – talk (i.e., translational research). Finally, and most importantly, my aim is to teach critical thinking skills which will transfer across domains. In any career, the ability to critically thi nk is imperative. However, research suggests that numerous adults in our society, including college graduates, employ flawed thinking. In a world where an enormous amount of information is a click away via the internet, students must not be passive observ ers but know how to judge, analyze, and synthesize the available information. I also strive to provide students with opportunities in which they can become an active agent in their own learning process through the use of writing, class/group discussion, an d questioning
