Eric's degree in Ecology & Evolutionary Biology means he studied the actual science behind APES — population ecology, species interactions, and ecosystem-level processes — not just the survey-course version. He teaches students to think about environmental problems the way an ecologist would, tracin...

Medical training reshapes how you think about environmental health — Amanda's MD/MPH work means she understands toxicology pathways, epidemiological data, and the public health consequences of pollution at a clinical level, which gives her a distinctive angle on APES units covering air and water qua...

Studying Human Biology at Stanford with a concentration in health policy gives Jake a direct line into the APES units on public health, pollution, and environmental legislation — he understands how ecological disruptions translate into real human consequences, which is exactly the kind of reasoning ...

Shawn's master's in chemistry gives him a molecular-level understanding of the processes that drive APES content — ocean acidification equilibria, nitrogen fixation pathways, ozone depletion mechanisms — so he can explain the why behind environmental phenomena instead of just naming them. He also te...

Premed coursework in human biology builds an intuitive grasp of the biological systems that APES questions test — nutrient cycling, population growth models, and the health consequences of environmental degradation aren't abstract concepts for Sharan, they're threads running through his own studies ...

Neuroscience teaches you to think about interconnected systems — how a single disruption cascades through networks of dependent processes — and Ankit applies that same framework to APES topics like trophic cascades, biogeochemical disruptions, and feedback loops in climate systems. His dual backgrou...

Todd's biology degree from UIUC gives him the ecological and cellular foundations that underpin APES topics like nutrient cycling, energy flow through trophic levels, and ecosystem disruption — and his social work training adds a surprisingly useful lens for the policy and human-impact questions tha...

Brown's public health curriculum digs into the human side of environmental problems — epidemiology, toxicology, resource policy — and Paul pairs that perspective with a biology major's understanding of the ecological systems APES actually tests. He teaches students to connect pollution sources to he...

Having earned her bachelor's in Environmental Science, Patricia didn't just survey APES topics — she studied biogeochemical cycles, soil science, and ecosystem dynamics at the college level they're drawn from. She zeroes in on the quantitative side students often underestimate, like calculating ener...

Having spent a year as a climate change researcher at the University of Helsinki — where she completed PhD-level atmospheric science coursework — Marika brings firsthand lab and field experience to AP Environmental Science. She digs into biogeochemical cycles, energy flow, and climate modeling with ...
