Lecturing, Supervision and Course Design
Mathematics and Statistics in Action Project 3: second year module taken by 82 maths students.
I wrote and delivered a mini lecture course on the application of complex networks to real world systems. The examination for 75% of this project was that of a group review of a scientific article based on an application of preferential attachment. The final 25% of the assessment was based on individual reflective journal entries.
Mathematics and Data Modelling Section 1: First year module taken by 140 engineering students.
Mathematics and Data Modelling: Section one of three: second year module taken by 135 engineering students.
I adapted and delivered 15 lectures on probability and statistics to give students in the department of automotive control and systems engineering a firm foundation in the subject. Assessment of this section was by way of class tests and exams, which I wrote.
Co-supervision of a master’s students dissertation. Their project is on the comparison of well-known machine learning algorithms and their accuracy at predicting missing data.
Conference Organisation and Outreach
Committee chair for the 41st Research Students’ Conference in Probability and Statistics My roles included: Scheduling, budgeting, database maintenance, invited speakers and accommodation. I delegated roles to members of the committee. Notable achievements include doubling the attendance of the previous year and a 50:50 gender ratio.
Local school activities
I have delivered presentations on mathematics in two local secondary schools. Each of these included a short presentation followed by a problem session I designed to give pupils a taste of different areas of maths taught at degree level they may not have encountered yet.
Sheffield Hallam Pop Maths
This light hearted annual mathematics competition involves almost 1000 students from the local area.
Ph.D. student outreach
I organised a half day event which consisted of 14 talks delivered by research students from Sheffield’s school of mathematics and statistics. The aim of this event was to display our postgraduates work and inform undergraduates about what a Ph.D. involves. Feedback from students was good across the board even requesting more events along the same vein.
I was a judge at the 2019 graduate students’ poster showcase.
This is where 2nd and 3rd year Ph.D. students present a poster to a non-specialised audience.
Undergraduate Research Internship
Using profit generated from the Research Students’ Conference in Probability and Statistics we decided to fund four week undergraduate research projects. For this Ph.D. students submitted project applications which were reviewed by a panel including myself. The best six were allocated funding and advertised to students. The aim of this scheme was to encourage minority groups to consider postgraduate research as a viable option.
I organised the recording of M.Sc. statistics modules for distance learning students and undergraduate modules for a student with sight issues. This role included liaising with module leaders, scheduling colleagues, uploading videos and dealing with issues.
