Our people

Ian Yule, Director

Professor Ian Yule started his career as a lecturer in agricultural engineering at Durham Agricultural College in the UK before moving to the University of Newcastle upon Tyne where he initiated research on precision agriculture. He came to Massey University as a senior lecturer in 1997. In 2000 he became the Director of the New Zealand Centre for Precision Agriculture and was made Professor in Precision Agriculture in 2011. Ian holds a PhD in agricultural engineering and has a passion for remote and hyperspectral sensing, as well as finding practical, usable solutions to problems within the agriculture space.  

Ian’s work is concentrated on contract research projects, research outputs and postgraduate supervision. Ian is the main supervisor to six full time PhD students and carries a $10M portfolio of contracted research activity. He has published extensively.



Kate Saxton
Project Coordinator

Kate's background is in project administration. She has a passion for project and event management, organisation and execution. Kate has a diploma in business and has been working at Massey for 10 years. Kate supports Professor Ian Yule and the NZCPA team.


Reddy Pullanagari

Reddy Pullanagari

Dr Pullanagari Reddy (Reddy) received a BSc degree in agriculture science from Acharya NG Ranga Agriculture University, Hyderbad Telangana India and a MSc degree in agronomy, Universit of Agriculture Science Bangalore, Karnatka, India. He then moved to New Zealand to pursue aPhD degree in remote sensing from Massey under the supervision of Professor Ian Yule. He subsequently joined as a research officer with the NZCPA group.

Dr Reddy's current research interest primarily focuses on mapping of vegetation features using multispectral and hyperspectral remote sensing tools and food quality inspection using hyperspectral sensors.


Ina Dragnova

Ina Draganova

Dr Ina Draganova is a Research Officer in the New Zealand Centre for Precision Agriculture. She received a BSc (Hons) degree in zoology and an MPhil degree in biology from Queen Mary University of London (UK) before completing her PhD in earth sciences at Massey University.

Prior to joining Massey, Ina was a lecturer at Hartbury College, University of West of England (UK) where she led the BSc animal behaviour and welfare programme. Her research interests lie in the area of animal management and precision farming. In recent years, Ina has focused on the use of emerging precision tools to track and monitor livestock and the use of aerial imaging systems in pasture management.


Gabor Kereszturi

Dr Kereszturi is a Research Officer at Massey University. He recently joined the Centre as a Hyperspectral Data Analyst. His current research projects focus on aerial surveying, data processing and spectra mapping from airborne hyperspectral remote sensing data from vegetated hillslopes.

Gabor holds a PhD in Earth sciences from Massey University and a master's degree in geography, majoring in Geographical Information Systems (GIS) and geomorphology from the University of Miskolc, Hungary.


Matthew Irwin

A tutor in GIS and remote sensing, Matthew teaches the software packages ArcGIS, ENVI, Terrset (Idrisi), ER Mapper and also manages a 10 machine GIS Lab and a variety of websites.

He has  been trained in using the ASD FieldSpec Pro, a spectroradiometer with a spectral range from 350 to 2500nm and a variety of GPS equipment, from handheld to RTK systems. He operates the airborne Specim Fenix hyperspectral sensor, the Flyspec and is the chief pilot for the UAV fleet.

Matthew holds a BSc (Hons) in Earth Science from Massey University. 


Eduardo Sandoval

Eduardo is the NZCPA technician, a role that includes maintenance; preparation, setting and analysis of samples and collection of biomass measurements (NDVI) through remote sensing devices.

His research interest is in the relationship between soil and pasture using high technology precision devices.

Eduardo has a masters degree in agriscience (Massey University), a Postgraduate Diploma in AgriScience (Massey University), a Bachelor in Agricultural Science (UC, Chile) and a Bachelor in Business Management (UNAP, Chile).



Sue Chok

Sue has a Bachelor of Engineering (Hons) specialising in Environmental Technology and Sustainable Energy from Massey University. After completing her degree she worked as a summer intern looking at the particle size and strength of New Zealand superphosphate. 

Her research topic for her PhD is Development of an automated fertiliser delivery control system in an aerial topdressing aircraft. 


Megan Cushanan

Megan spent 15 years as an agronomic consultant in the sports turf industry before beginning her PhD. Megan has advised on many different types of turf throughout the world and has significant experience in warm, cool and transitional climates. She has presented over 100 talks in New Zealand and abroad. In addition to her consulting experience, Megan has tutored turf and horticulture students in New Zealand and Hong Kong. 


Istvan Hajdu

Istvan received his master’s degrees in geological engineering and geography from the University of Miskolc, Hungary. He has worked as a GIS technician and a GIS Data and Mapping Officer. This sparked his interest in the utilisation of GIS, remote sensing, image analysis and data processing in studying the Earth's land surface interactions.

His PhD research is focussed on the importance of soil moisture content of the land surface. 


Pip McVeagh

After completing undergraduate study in landscape management at Massey University, Pip gained a postgraduate diploma focusing on GIS, remote sensing and landscape management. She worked for the New Zealand Centre for Precision Agriculture (NZCPA) for a number of years. Today she is undertaking a PhD as part of the PGP project with Ravensdown focussing on site-specific pasture production in New Zealand hill country. 


Tommy Cushnahan

Tommy had a career lasting nearly 20 years in the golf design and construction industry.

Tommy is undertaking his PhD study with the NZCPA, and his topic is "Hyperspectral Remote Sensing and Imaging".

Tommy holds a BSc (Hons) in Turf Grass Science (First Class), University of Central Lancashire and a MSc in Golf Course Architecture, Herriot Watt University.
