- Unmatched crop diversity: Tailor your research to your exact passion. Our students work across a massive range of species - whether you are maximizing yields for major commodities like corn, wheat, forages and soybeans, or innovating with vegetable crops, fruits, berries, elite turfgrass, trees and ornamental landscapes.
- Beyond the classroom: It's about more than just the classroom and the lab when you study with us. You'll get the chance to shape your own graduate experience, build an unstoppable professional network and belong to a community that has your back. Plus you'll have the opportunity to become an active member of the HCS Graduate Student Association (HCS GSA) - an organization run entirely by graduate students, for graduate students.
- Here's how the HCS GSA elevates your time at Ohio State:
- Instant community: From welcoming you on day one to hosting regular social hangouts, we make sure current and incoming students plug directly into a supportive, collaborative crew.
- Professional edge: Level up your career potential through exclusive networking events, professional development workshops and industry connections that go way beyond the classroom.
- Your campus voice: We serve as the direct liaison between the graduate student body and departmental administration, ensuring your ideas, feedback and needs are always heard.
- Student-led innovation: This is your forum to pitch, plan and execute the academic and social events you want to see happen within HCS.
