This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Prachee Avasthi rather than just read about it. In short: Prachee Avasthi (born 1979) is a Professor of Anatomy and Cell Biology and Science Communicator at Dartmouth College and a co-founder, chief scientific advisor, and incoming CSO at Arcadia Science in Berkeley, California. She works on upwardly motile Chlamydomonas reinhardtii and is on the Board of Directors of eLife.

Key takeaways

Prachee Avasthi belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Prachee Avasthi to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Prachee Avasthi from memory before moving on to harder problems.

Reference excerpt

Prachee Avasthi (born 1979) is a Professor of Anatomy and Cell Biology and Science Communicator at Dartmouth College and a co-founder, chief scientific advisor, and incoming CSO at Arcadia Science in Berkeley, California. She works on upwardly motile Chlamydomonas reinhardtii and is on the Board of Directors of eLife.

Early life and education Avasthi studied integrative physiology at the University of Illinois at Urbana–Champaign. During her undergraduate program she worked on insect classification and synaptic plasticity. She became more interested in the brain, and earned her PhD in neuroscience under the supervision of Wolfgang Baehr at the University of Utah. During her doctoral studies she investigated how cilia help our eye's photoreceptors detect light. She was a postdoctoral researcher with Wallace Marshall at the University of California, San Francisco. Here she began work on Chlamydomonas reinhardtii, a model organism for studying cilia. Cilia function requires normal cilia length and motility, and Avasthi identified that the dopamine binding G protein-coupled receptors (GPCRs) were the most regularly involved with flagellar length regulation.

Research and career Avasthi uses Chlamydomonas reinhardtii, a unicellular green alga, to investigate the assembly of cilia. She was particularly interested in the cellular machinery needed to maintain cilia, and used small molecule chemical inhibitors to identify important features in ciliary transport. Avasthi found that actin, a cytoskeleton protein, was required for intraflagellar transport (IFT) regulation in Chlamydomonas reinhardtii. The actin is recruits IFT to basal bodies during the elongation of flagella; and without actin the flagellar length is lost. She saw the same impacts using a myosin inhibitor, which suggests that actin may use a myosin pathway. In 2015 Avasthi started her own research group at the University of Kansas Medical Center, which is supported by the National Institutes of Health. She combines chemical biology and biochemistry with genetics to understand the mechanisms that regulate assembly of the cilium. In 2018 she was awarded an NIH R35 Outstanding Investigator Award.

Academic service Avasthi is enthusiastic about reforming scientific research culture, helping early career researchers set up their own laboratories. She launched New PI Slack, an online space for over a thousand new Principal investigators to share notes and ideas. Avasthi supports preprints and the reform of scientific publishing, and is on the Board of Directors of eLife and ASAPbio. In her laboratory she leads a preprint journal club, where members of her group read and review new material, providing feedback to authors.

Worked examples

Example 1 — a first encounter with Prachee Avasthi

Start with the simplest possible case. Write down what Prachee Avasthi claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Prachee Avasthi before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Prachee Avasthi ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Prachee Avasthi

In research: Prachee Avasthi appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Prachee Avasthi in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Prachee Avasthi is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1979 births, 21st-century women biochemists, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Prachee Avasthi outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
