Cornell training, African impact.

The Cornell Assistantship for Horticulture in Africa (CAHA) provides funding for a doctoral student from sub-Saharan Africa to complete course work at Cornell and conduct dissertation research primarily in Africa under the supervision of a local thesis advisor.



  • must already have a Master's degree
  • originate from a country in Sub-Saharan Africa, excluding South Africa
  • be of native African ancestry


Depending on the nature of the research and cost, it may be necessary for the student to secure additional outside funding. The assistantship will require 15 to 20 hours per week of teaching and/or research responsibilities. Acceptance into the program is contingent on the student's agreeing to return to sub-Saharan Africa after completion of the doctoral degree. 

Applications are now closed. Check back in 2024 for the next application round!

CAHA's Origin

CAHA was founded in 2006 thanks to a generous gift from Chris Wien, M.S. ’67, Ph.D. ‘71, professor emeritus of horticulture. In the 1970s, Wien spent time working in Africa at the International Institute for Tropical Agriculture. That experience awakened him to the continent’s need for greater support in horticulture education.

Climate Change

Potato may help feed Ethiopia in era of climate change

With unpredictable annual rainfall and drought once every five years, climate change presents challenges to feeding Ethiopia. Adapting to a warming world, the potato is becoming a more important crop there – with the potential to feed much of Africa.


Plant breeding project gives East African farmers better leafy green option

Phillip Griffiths of Cornell AgriTech has a special connection in East Africa that’s improving the humble collard green to help smallholder farmers—and their communities—live and eat better.

Life. Changing.

The Sweet gift of Knowledge

Kalenga Banda studies horticulture not just because of a love of plants, but a love of people.
