Meet the MASH team

Academic Skills Advisors

Pete Hart (MASH Team Leader)

I joined the MASH team in 2020 and I have been the team leader since April 2023. I'm extremely proud of the wonderful MASH team, we're here to help when you need us!

Before joining the University, I worked teaching maths at school and sixth form level. This experience taught me a great deal about helping learners of all ages.  At MASH, we aim to provide friendly and patient assistance to anyone who might need it.

Will Morgan

I started work as an Academic Skills Advisor for MASH in September 2022. Prior to that I have built up a wealth of experience teaching in many different contexts - University, Secondary schools, Primary schools, Private Tuition and Adult Education.

I gained a PhD in Pure Mathematics in 2010 from the University of Loughborough. It is through a fascination for how things work and seeing Mathematics as the language in which we can best have that conversation that led me to this point. Treating Mathematics as a language has been a principle I have maintained throughout my teaching. I hope my enthusiasm for Mathematics is infectious, I love to teach with humour! No one should feel excluded from any part of their education because of any Mathematical barriers that arise. Helping students overcome those barriers and seeing the pride and sense of achievement that often brings is the best feeling as a teacher.

Poppy Jeffries

I started working as an Academic Skills Advisor in July 2023, after joining the MASH team as a Tutor in 2022. I'm also a Mathematical Ecology PhD student in SoMaS, using applied maths techniques to understand the behaviour of seabirds, and I've been a GTA there since 2019, teaching on a range of mathematical modules in SoMaS and Engineering. I love working at MASH, and supporting students from across the University.

Maths Tutors

Andrew Neate

I joined MASH as a maths tutor in 2023. I'm also a pure maths PhD student in SoMaS looking at enriched category theory (feel free to ask me about this!). At MASH I'm always looking for new ways to think about mathematical ideas and explain them in more intuitive ways.

Oliver Spencely

I work in the department of mechanical engineering. I've returned to university after working for 6 years in engineering and management roles and I'm thrilled to be here helping students learn maths.

Stats Tutors

Erika Siregar

I joined the MASH team in September 2025. I am also a PhD student in Data Science at IJC where my research explores how social media data and machine learning can be used to understand small businesses online activities.

Before starting my PhD, I worked as a statistician and data scientist at Statistics Indonesia and contributed to collaborative projects with other organisations. My experience spans applied statistics, data analysis, and programming. I particularly have a strong passion for R and co-founded R-Ladies Jakarta, the Jakarta chapter of the global R-Ladies community that promotes gender diversity and inclusion in the R programming world.

I particularly enjoy supporting students from all disciplines in building confidence with statistics and data analysis, helping them see how these skills can make their studies and research both meaningful and enjoyable.
