Biography

Professor Alexandra (Alex) Johnstone

Alex is a member of the Rowett Institute Executive Committee, as Theme Lead for Nutrition, Obesity and Disease. Alex obtained her PhD in 2001 and she is a UK registered Nutritionist with Association for Nutrition.

My ORCID ID is : https://orcid.org/0000-0002-5484-292X

‘Working on safer, fairer, healthy and sustainable food for all’

She currently leads the £1.6M ‘FIO Food’ research grant, funded from UKRI Transforming Food Systems, which is research on Food Insecurity and Obesity, with emphasis on the retail food sector. Also the £0.5M ‘DIO Food’ grant on diet and health inequalities.

/rowett/research/fio-food/index.php

/rowett/research/dio-food-1857.php

These grants aim to:-

-Improve environmentally sustainable and healthier food choices in the UK food system, with focus on policy for the retail food sector

-Provide actionable evidence for retail strategy policy addressing dietary inequalities in two vulnerable groups - people living with obesity and food insecurity.

She manages a research team to successfully lead high calibre research activities, in collaboration with internal and external colleagues. She is actively engaged in organising and delivering teaching/learning excellence and the translation the team’s innovative science to a range of stakeholders, to achieving high impact, through sustained knowledge exchange activities, and having real commercial and community benefit.

 

My research team includes (March 2024):

Dr Marta Lonnie, Research Fellow

Claire Fyfe, Research Technician

Annika Bucky, PhD student 

Nouf Alkhattabi, PhD student

Research

Research Overview

Major achievements I have over 100 peer-reviewed publications supported by UKRI, EU funding and Scottish Government. My h-index, based on papers indexed in Scopus, is 38. 50% of my papers have more than 10 citations, with 9 papers with over 100 citations (Scopus, 26/01/23). I have raised over £8M in grants, to support my research. My research strategy has been to investigate the effect of diet on appetite control and energy balance. This has been driven by developing understanding of protein induced satiety and a strategy to systematically examine the effect of amount, type and timing of nutrient intake on energy balance. My main role has been as a UK research scientist to advance understanding of human nutrition, based at the Rowett Institute; but the extensive translation of my research for impact, is of key importance to me.

Knowledge Exchange

Public engagement is one of my key strengths. I regularly contribute regularly to radio, television and printed press and has often contributed to The Conversation, the online blog. Many of my public outreach activities, have been funded by small grants. Examples include, online resources for schools to celebrate the centenary of the discovery of insulin; > 3000 pupils participated in this event (2021/22). In March 2023, I delivered activities around healthy sustainable diets, as part of British Science week, involving a CPD event for teachers, workshops for families, together with whole school and community events.

In recognition of my public engagement (Café Scientifique, Café Med, Pint of Science, TechFEST, Soapbox Science, Explorathon and International Women’s Day), I received the Principal’s Award for Knowledge Exchange (2018). She was also and in 2021 was cited as one of , tackling the biggest health challenges of our time in the UK BioBeat award ‘Movers and Shakers in BioBusiness.
