Natural Sciences (Biological)

The Natural Sciences Tripos is the framework within which sixteen different Faculties and Departments at Cambridge deliver undergraduate training in a wide range of physical and biological sciences, as well as the history and philosophy of science. Students apply to study either Natural Sciences (Biological) or Natural Sciences (Physical).

Course overview

The Natural Sciences Tripos provides students with a multidisciplinary scientific background, increasingly important in modern science, before allowing them to specialise in their chosen subject. The course therefore provides the intellectual breadth and depth which allows students to both experience new areas of science and to make connections across traditionally discrete disciplinary boundaries, substantially enriching their understanding of their specialist subject. All Natural Sciences students study for three years, leading to a BA degree, and some continue to study for an additional fourth year, leading to a MSci degree.

Biological science subjects at Cambridge include:

  • Biochemistry
  • Genetics
  • Pathology
  • Pharmacology
  • Physiology, Development and Neuroscience
  • Plant Sciences
  • Psychology
  • Zoology

There is significant flexibility, however, within the Tripos, and students admitted to Natural Sciences (Biological) can choose from a variety of courses (including biological and physical science options), although specific subjects have essential or desirable prerequisites.

What is it like to study Natural Sciences (Biological) at King’s?

Given the diversity of choices, a typical week is hard to define. Cornerstones include lectures and practical classes in the Faculty and supervisions in King’s. Each contribute to building your knowledge, aptitude, and reasoning in the chosen subject. Supervisions are small group (usually one to three) interactive sessions which occur once a week per subject and give time to reflect on the learning for the week, ask questions about the material, and integrate information. Supervisions often include set work to cement the understanding, which may take the form of essays, presentations, or problem sheets. King’s typically admits approximately six Natural Sciences (Biological) students per year.

 

What do we look for in an applicant to Natural Sciences (Biological)?

Biological Natural Sciences is well suited to naturally curious individuals with a keen interest in exploring why the natural world is the way that it is. We are interested in how you think, what excites you, and how you approach the unknown, not simply in what you already know. Great Natural Scientists are comfortable with the unknown; this is where discoveries happen.

 

Requirements

A Level: A*A*A

IB: 41-42 points overall with 7, 7, 6 at Higher Level 

Subject requirements: Mathematics and any two other science or maths subjects from Biology, Chemistry, Physics, and Further Mathematics

Admissions assessment: Engineering and Science Admissions Test (ESAT)

Written work: None

 

Admissions assessment

Candidates for Natural Sciences (Biological) must take the ESAT, which is a pre-registration required test. The Mathematics 1 module is compulsory for all candidates, and you will then need to complete two additional multiple-choice modules from Biology, Chemistry, Physics, and Mathematics 2. For more information about the test, please see the University website.

 

Careers and graduate opportunities

The Natural Sciences course prepares students well for the challenges of research, especially in emerging, interdisciplinary areas. Many graduates continue with further study or research, and many go directly into a broad range of careers, including programming and software development, financial management, management consultancy, and teaching.

 

What is the best thing about studying Natural Sciences (Biological) at King’s?

Natural Sciences is one of the larger subjects in the College, supported by a good number of Fellows, hence students are part of a strong and supportive cohort. King’s is fortunate to be able to offer funded research internship opportunities through its Summer Research Programme, and biological natural scientists regularly make successful applications to gain research experience and work in research laboratories across Cambridge during the summer vacation, in some cases leading to publication. King’s has a long history of notable biologists - former Fellows include Nobel laureates Fred Sanger (two Nobel prizes!) and Sydney Brenner. Perhaps the next one could be you!

 

A top tip for applicants to Natural Sciences (Biological) at King’s

Sebastian Eves-van den Akker

Bio

Sebastian is a geneticist, and Head of the Plant-Parasite Interactions group, with an interest in the genes that control a dialogue between kingdoms of life: the two-way molecular communication between plants and their parasites. He develops understanding from the position that the two organisms are one interlinked entity, studying the biology of the entire host-parasite complex. He uses genetics to dissect the communication between the two organisms, to understand how evolution drives novel forms and functions, through a development-altering relationship, that is phylogenetically and geographically widespread.

Recent highlights from the lab exemplify the fascinating biology of the study system, the connectedness of the kingdoms, and the central thesis that the two organisms are best studied when considered as one entity. The lab showed that: i) host and parasite each contribute to the cross-kingdom synthesis of Vitamin B5, defining the hologenome theory of susceptibility-gene discovery (Siddique et al., 2022, Nature Communications); ii) the nematode has evolved a novel form of precisely guided somatic genome editing to generate thousands of new transient effector alleles (Sonawala et al., 2024, Cell Genomics); and iii) that the nematode mobilises and ingests parts of the plant genome during infection (Ko et al., 2023 Molecular Biology and Evolution).

Iris Hardege

Bio

Iris Hardege is a Royal Society University Research Fellow at the Department of Zoology, where she is interested in understanding how complex behaviours arise from anatomically different brain structures across the animal kingdom. Currently her research predominately focusses on the study of the surprising complexity of neurotransmitters and their receptors in the model organism C. elegans, and how they contribute to the generation of complex behaviours such as learning.

Iris completed her PhD in Medicine at the University of Cambridge in 2017 under the supervision of Dr Kevin O'Shaughnessy, where she studied potassium channels in the adrenal gland and their contribution to rare genetic forms of hypertension. She then went on to do postdoctoral work at the MRC LMB with Dr William Schafer to study ion channel receptors in C. elegans. In 2023 Iris started her own group at the Department of Zoology funded by a Royal Society University Research Fellowship.

Barry Keverne

Bio

Professor Keverne has long standing experience in behavioural neuroscience and has, in the past 10 years, brought molecular genetic techniques to focus on brain development and investigate how genetic perturbations of the brain influence brain function. In particular he has employed androgenetic and parthenogenetic chimeras to understand how the imprinted genome influences brain development and has extensively investigated the adult phenotype of mice carrying a mutation in paternally expressed genes. These studies have led to a co-adaptive evolutionary theory of brain and placental development through genomic imprinting. Pheromonal influences on behaviour and endocrine responses in mice is also a long standing interest and in recent years, together with Piers Emson, he has investigated pheromonal signalling via Erk and Akt phosphorylation to enhance vomeronasal neural regeneration survival.

Nile Stephenson

Bio

Nile is the Roger Evans and Aey Phanachet Research Fellow in Co-evolution and Symbiosis. He is based in the Department of Zoology. His research broadly encompasses understanding how ecosystems change in time and space. In his fellowship, Nile will be focussing on how the ecological dynamics of coral reefs change as they experience the effects of climate change. In his work, he uses a range of mathematical models and field techniques to assess whole-ecosystem processes on coral reefs in the Seychelles, integrating spatial maps of coral reefs, behavioural data on sharks, and environmental data. A key aspect of his work is disentangling the drivers of ecosystem stability, and seeking to understand the fundamental properties that contribute towards stable states in ecology. He is also interested in how ecosystems have changed through deep time, particularly focusing on critical transitions in evolutionary history such as the evolution of animals.

Nile studied at Aberystwyth University and the University of Exeter before his PhD at the University of Cambridge (St. Catharine’s College), which he completed in 2025.

Marco Tripodi

Bio

Marco’s primary research interest lies at the interface between action and spatial cognition. He is interested in understanding how animals construct mental representations of space and use these to guide their actions. His work has uncovered the organisational principles of spatial-motor representations in the brain1 and the logic governing sensory-motor alignment2. More broadly, his research has begun to highlight the integral role of motor circuits in shaping both perceptual and cognitive processes and to define the molecular identity of the neural populations involved.

Marco’s additional significant contributions include advancements in the field of motor control3 and the development of methods to map and manipulate neural circuits4.

He leads a research group at the MRC Laboratory of Molecular Biology and he has been the recipient of Starting and Consolidator ERC grants.
