Part II Pharmacology
There are two ways of studying pharmacology in Part II of the Tripos. Both share the same core teaching, but they differ in whether they include a practical research project (Part II Pharmacology) or a library dissertation and an additional single-paper Minor Subject (BBS). There is no practical work in the pharmacology component of the BBS course. Teaching takes place only during the Michaelmas and Lent Terms. The Easter Term is reserved for revision and exams.
Both courses can be equally demanding, but if you are considering postgraduate laboratory-based research (PhD or MB/PhD), you are strongly advised to take Pharmacology Part II. Most universities will expect applicants for such research degrees to have had the sort of laboratory experience that the Pharmacology Part II course provides.
Biological and Biomedical Sciences
|Laboratory-based research project|
|Library-based dissertation on a topic chosen from titles in Pharmacology or Minor Subject|
|Additional Minor Subject (chosen form a wide range).|
Most teaching is delivered by staff from the Department of Pharmacology. There are presently 18 University Teaching Officers and a number of senior researchers within the department. All are actively engaged in research and committed to teaching. Visitors from other departments and pharmaceutical companies complement the expertise of staff by providing some lectures and by supervising research projects. Weekly Tea Talks, which all students are expected to attend, provide a roughly equally mix of talks from the home team and from visitors. All lecturers are available to provide supervisions.
- The course aims to provide a balanced, critical and wide-ranging treatment of pharmacology as it relates to understanding mechanisms of drug action. It is not a course on therapeutics, although its focus on underlying mechanisms provides insight into both drug development and the use of drugs to treat disease. There is some emphasis on areas that reflect the research interests of teaching staff, although those interests range widely form molecular to behavioural pharmacology. By teaching to the bounds of current knowledge, the course aims to impart the excitement of current research in pharmacology and highlight some of the current controversies.
- The course educates students in a range of learning skills to equip them for careers in medicine, veterinary medicine and science, and for careers unrelated to pharmacology.
- For Part II Pharmacology students, the course educates students in practical skills to equip them for careers in medicine, veterinary medicine and science.
- To offer a course of lectures, tech talks, discussion groups, a statistics workshop, supervisions and tea talks in pharmacology. Lectures lie at the core of the course and define the syllabus. Tech talks, usually provided by senior research fellows, provide advanced reviews of techniques currently used in pharmacology. Discussion groups provide opportunities to present and critically evaluate the scientific literature, to review the presentations of your peers, and to present progress reports on projects or dissertations. Supervisions are available on all lecture courses. They allow issues arising from lectures or further reading to be pursued, and they provide opportunities for students to submit written work for comment. Tea talks are formal research presentations from internal and visiting speakers, which all students are expected to attend.
|To offer a laboratory-based supervised research project.||To offer a supervised library-based dissertation topic|
|Assessment is by written examinations. Past examination papers are available on-line. Candidates may also be required to attend an oral examination. In addition, the following means of assessment are specific to either of the two courses:|
|The research project is assessed by a report from the supervisor, submission of a written report, and assessment of a formal research seminar.||The research dissertation is assessed after submission of a written report and in an oral examination.|
At the end of the course students should be able to:
- Think critically and with an appropriate level of knowledge across a range of pharmacological topics.
- Effectively retrieve, evaluate and assimilate information from the scientific literature.
- Assess the feasibility of published methods to solve pharmacological problems.
- Communicate effectively with a scientific audience in oral and written presentations.
- Analyse and assess research methods and results during a supervised research project (Part II Pharmacology only).
Organization of the course
A lecture and work in small groups at the beginning of the course provides guidance on accessing the scientific literature and writing essays, and advice on careers.
About 100 lectures are provided, divided between Systems Pharmacology, and Molecular and Cellular Pharmacology. The groupings are more administrative than real: there is a seamless continuity between molecular mechanisms and the higher order levels of biological organisation. Lectures are timetabled to allow you to attend them all. With no more than 2+hours/day spent in lectures, there is plenty of time to explore specific topics in considerable depth through the primary literature. There is some weighting of lectures towards the Michaelmas Term (when there are sometimes two lectures/day). This leaves more time in the Lent Term (usually 1 lecture/day) for projects and dissertations. As with most Part II courses, there are no Saturday lectures. You can expect to encounter the most recent research and the controversies surrounding it. The lectures shown are typical, but each year there are some changes to accommodate staff changes, sabbatical leave, etc.

There are 8 tech talk sessions, some of which cover more than one topic. They are delivered weekly in the Michaelmas Term and aim to provide a comprehensive overview of a wide variety of advanced techniques currently used in pharmacology research. They are usually delivered by senior research fellows with first-hand expertise in the techniques they discuss. Tech talks provide essential background to critical evaluation of materials presented in lectures, and are thereby an essential and integral part of the core course. For Part II students, they additionally provide a foretaste of techniques that may be encountered in research projects. Topics, which may vary between years, have recently included:
- Molecular biology
- Protein expression and detection
- Protein purification and reconstitution
- Biophysics and structural analysis
- Imaging applied to cell signalling
- siRNA and transgenics
- Behavioural techniques
You will be allocated to a discussion group of about 10 students with 2+ teaching staff as soon as you join the department. Early in each term, you will agree a timetable for your meetings and you are then expected to attend all meetings of the group. The exact format of the meetings varies between groups, but each seeks to develop presentation skills and the ability critically to evaluate the scientific literature.
We attach considerable importance to supervisions: all lecturers in the Part II course are required to provide supervisions. Supervisions are likely to be in larger groups than at Part I, but they will almost invariably be given by the person who delivered the lectures. Lecturers will also mark essays. The onus rests more with you than at Part I to arrange supervisions: most lecturers provide a sign-up sheet.
These are held weekly during term and comprise a mix of external and internal speakers talking about their recent research. They are followed by drinks and nibbles; providing a relaxed chance to catch up with the speaker and everyone else in the department.
The list of projects is issued in early November. Over a few days, each project supervisor is then available to discuss potential projects. The allocation of students to projects is left entirely to the Part II class. Most projects are within the research labs of staff of the department, but a few projects are based elsewhere (e.g., Clinical Pharmacology). You will spend about 3 days/week working on your project (24 days in total). Many students find this to be the most rewarding part of the course, and it is not uncommon for work arising from a Part II project to be published or presented at scientific meetings. Several former students have won national prizes for their projects. For students contemplating a research career, this may be the first real taste of what it involves. The project is submitted as a written report (in the style of a published paper) and presented as a talk to the entire department in Easter Term. Recent project titles include:
- Oxidative-stress induced changes in ABC efflux transporters in brain endothelium
- Actions of nitric oxide-releasing non-steroidal anti-inflammatory agents on smooth musclee

Minor Subject (BBS only)
Detailed arrangements for the minor subjects differ between subjects. You can obtain further details from the web site and from the course booklet for BBS. The timetables below do not include the minor subject details.
There are 4 written papers in Pharmacology. Each paper carries equal marks. All 4 papers are taken by all candidates from BBS and Part II Pharmacology. For Part II Pharmacology students, the research project contributes 20% of the total mark. For BBS students, the dissertation and Minor Subject paper contribute with the marks from the 4 written papers to the final mark. All BBS candidates have an oral examination on the subject of their dissertation. The examiners may also invite candidates from either course for an oral examination on any part of the course. There is no written practical examination for either course.

The maximum number of students allowed onto the Part II Pharmacology course is 30, and determined by the number of research projects available. Our selection policy is to accept students with the best overall marks in Part IB examinations. Where necessary, the mark in Part IB Pharmacology or MODA serves as a tie-breaker. Students from MVST and NST are treated identically. For admission to the BBS course, students will be expected to have an adequate background in pharmacology evident from performance in MODA or Part IB Pharmacology. There are up to 20 places for BBS Pharmacology. There are no interviews and no application need be made other than on the list of Part II preferences submitted through your College. Prospective applicants are invited to contact Professor Taylor or any of the teaching staff if they have any queries about the courses.
