Amy Okamura-Cho, studying for Bachelor of Medical Sciences 2014

Amy is a medical student who spent a year with my group doing two systematic reviews of vitamin D treatment for people with chronic kidney disease. Amy completed both reviews that included over 164 randomised trials and 10,000 people with kidney disease, showing that even a substantial number of research trials is not enough to prove whether vitamin D is helpful treatment. A big achievement. Well done, Amy!

Katrina worked in my group in 2014. In that short time she has completed two very large systematic reviews and started work on a third. Well done Katrina. We wish Katrina well in her next endeavours.
