Pedro Bello

Pedro Bello

Staff Research Associate II


Pedro Bello has a B.S. degree in Systems Analysis and a graduate degree in Strategic Management of Information Technologies from the Pontifícia Universidade Católica de Campinas in Brazil. At UC Davis, Pedro gathered vast experience in seed research working with professor Dr. Kent Bradford for over 7 years. He is specialized in the assessment of seed quality, vigor and storage life. He has been developing efficient tools and mathematical models for new seed technologies. His innovations on the analytical equipment for single-seed respiration measurements (Q2 Scanner) made the information from the instrument useful and more accessible to users around the world.

Shuangshuang Liu


Ph.D. Student


Shuangshuang Liu is a Ph.D. student in the Horticulture and Agronomy Graduate Group here at UC Davis. She received her B.S. and M.S. in grassland science from China Agricultural University. Her research interest focuses on hydrothermal-time modeling of environmental influences on seed germination and their genetic basis.

Mohan Niroula

Ph.D. Student


Mohan Niroula is a Ph.D. student in the Horticulture and Agronomy Graduate Group here at UC Davis. He did his undergraduate with Plant Breeding and Genetics as an elective from Punjab Agricultural University, Ludhiana, India and received his Master's in plant pathology from UC Davis. Mohan is currently involved in a project related to genetic and environmental interactions affecting lettuce seed dormancy and quality funded by the Western Regional Seed Physiology Research Group.

Alfred (Heqiang) Huo

Alfred Huo - Copy

Postdoctoral Researcher


Dr. Alfred (Heqiang) Huo is a Postdoctoral Researcher. He earned his doctorate from the University of Georgia in the field of Horticulture in 2008. Currently, he is working on an USDA project to characterize one candidate gene, LsNCED4, which might control thermo-dormancy in lettuce. He is using genetic and molecular tools to study the functions of LsNCED4.


Peetamber Dahal

Peetambar Dahal

Staff Research Associate


Dr. Peetambar Dahal is a Staff Research Associate who has worked in this capacity in the Bradford lab since 1993. He is in charge of managing the lab and conducts research on a wide range of topics related to seed biology and quality. Currently, he is measuring expression of a number of hormone-related genes in lettuce seeds in relation to seed dormancy.


Yajing Guan




Lingqi Kong



Lingqi Kong is a visiting Scholar from China Agriculture University. Lingqi has joined the Bradford Lab for the next two-years.

Fei-Yian Yoong

Ph.D. Student


Fei-Yian Yoong is a graduate student in the Bradford lab. Originally from Malaysia, she graduated with a Bachelor's degree in Plant Biotechnology from UC Davis in 2007. She spent one year working in Monsanto-Calgene campus as a Research Assistant. She is currently involved in an NSF-funded project, that is related to QTL mapping on thermodormancy and other breeding traits in lettuce seeds. 

Jacson Zuchi

Visiting Ph.D. student


Jacson Zuchi was a Visiting Scientist in the Bradford Lab in 2010. He graduated with a degree in Agronomy in 2006 and completed his M.Sc. in Seed Science & Technology in 2008, both at the Federal University of Pelotas (Brazil). Currently, he is a Ph.D. candidate in the Plant Sciences Department in the Federal University of Viçosa (Brazil). He works with seed storage, looking for ways to slowdown seed deterioration.

Andres Schwember

Ph.D. Student


Andres Schwember completed his Ph.D. in 2009 as a member of the Bradford Laboratory in the Plant Biology Graduate Group at UC Davis. Originally from Chile, he also worked in the seed industry in Brazil before coming to UC Davis to first do a MS degree and subsequently is pursuing a PhD. His research focused on the effects of seed priming on the storability and longevity of lettuce seeds. He pursued a number of genetic and physiological approaches to understand why seed priming sometimes reduces seed storage life. His project was funded by the Western Regional Seed Physiology Research Group.

Frances Rond

Graduate Student Researcher


Frances Rond was a Ph.D. candidate in the Horticulture and Agronomy Graduate Group at UC Davis. She graduated from CSU, Fresno with a B.S. and M.S. in Plant Science.  A member of the Bradford lab through June 2010, her research focused on the maternal environment’s influence on gene expressions in lettuce seed dormancy and development. This work was funded by the Western Regional Seed Physiology Research Group.

Dr. Irfan Afzal

Fulbright Scholar


Dr. Irfan Afzal is an Assistant Professor at the University of Agriculture, Faisalabad, Pakistan. He is in the Bradford lab from October 2007 through July 2008 as a Fulbright Scholar. Dr. Afzal's interests are in seed priming and salinity tolerance.

Keshavulu Kunosoth

Visiting Scientist


Dr. Keshavulu Kunosoth was a Visiting Scientist in the Bradford laboratory through April 2010.
