About David

Bio

I am an expert in ecology, conservation biology, zoology, wildlife biology, and biological statistics, holding dual Ph.D.s in Zoology and Ecology, Evolutionary Biology & Behavior from Michigan State University, and a B.S. magna cum laude in Conservation Biology from Arizona State University.

Over the past 15+ years I have worked as a research scientist, field ecologist, and faculty member at Oregon State University, publishing more than 20 peer-reviewed papers in journals like Ecology,...

I am an expert in ecology, conservation biology, zoology, wildlife biology, and biological statistics, holding dual Ph.D.s in Zoology and Ecology, Evolutionary Biology & Behavior from Michigan State University, and a B.S. magna cum laude in Conservation Biology from Arizona State University.

Over the past 15+ years I have worked as a research scientist, field ecologist, and faculty member at Oregon State University, publishing more than 20 peer-reviewed papers in journals like Ecology, Journal of Animal Ecology, and Philosophical Transactions of the Royal Society B.

My tutoring strengths are rooted in how I actually do science. I've built statistical models in R and JAGS, designed field studies across sub-Saharan Africa and the Pacific Northwest, and supervised student researchers at every level from undergrad to graduate. I know where students get stuck — not just in textbooks, but in real data, real analysis, and real scientific reasoning — and I'm good at meeting people exactly where they are.

Subjects I tutor: ecology, conservation biology, zoology, wildlife biology, environmental science, evolutionary biology, biostatistics, biological statistics, and research methods. I'm also well-suited for graduate-level statistics (R, Bayesian modeling, occupancy models), scientific writing, AP Biology, AP Environmental Science, and GRE prep — including the Biology Subject Test.

Whether you're working through AP Biology, struggling with a graduate ecology or statistics course, or trying to make sense of your first research dataset, I bring both the depth and the patience to help you get there.

Approved Subjects

Environmental Science

Environmental Science

I hold dual Ph.D.s in Zoology and Ecology, Evolutionary Biology & Behavior from Michigan State University, with over 15 years of hands-on research experience spanning ecosystem assessment, biodiversity monitoring, species distribution modeling, and natural resource management across three continents. As former Associate Research Faculty at Oregon State University, I led multi-agency environmental research programs across the Pacific Northwest, producing decision-support tools directly adopted by federal land managers at USFWS and the National Park Service. My work integrates statistical modeling (R, JAGS, ArcGIS), field data collection, and environmental compliance frameworks including NEPA and ESA — the same tools and concepts covered in undergraduate and graduate environmental science curricula. Whether you're tackling AP Environmental Science, an undergraduate ecology course, or a graduate-level research methods class, I can connect textbook concepts directly to how environmental science is practiced in the real world.
Zoology

Zoology

I hold dual Ph.D.s in Zoology and Ecology, Evolutionary Biology & Behavior from Michigan State University, where my doctoral research focused on wildlife population dynamics, animal behavior, and multi-species community ecology in one of the world's most biodiverse ecosystems — the Mara-Serengeti of East Africa. Over 15+ years of field and academic research I have studied carnivore ecology, predator-prey dynamics, behavioral ecology, and vertebrate biology across sub-Saharan Africa and the Pacific Northwest, publishing more than 20 peer-reviewed papers in top journals including the Journal of Animal Ecology and Philosophical Transactions of the Royal Society B. I have supervised student researchers in the field and classroom at every level, and my teaching approach connects foundational zoology concepts — animal physiology, taxonomy, evolutionary biology, vertebrate and invertebrate biology — directly to real organisms and ecosystems rather than abstract textbook examples. From introductory zoology and AP Biology to advanced vertebrate ecology and graduate-level animal behavior, I bring genuine field expertise and publishing experience that few tutors in this subject can match.
