About me

About me:

I am a postgraduate researcher at Durham University, specialising in cell biology. I've always had a passion for science, and didn't actually make up my mind for which area of science I wanted to pursue until I got to university. Hence, I have done chemistry, physics, mathematics, and biology at A level.

I am keen to see the same infectious enthusiasm for science in others, and I believe in simple, engaging tutoring sessions to ensure this. I have tutored both younger children aged 10-12, and university undergraduates in science and biology.

Tutoring sessions:

My primary aim is to solidify your understanding of the subject at hand, while simultaneously working towards set goals such as essays or exam based assessments. Whatever your needs be, I am eager to discuss them with you and figure out the best course of action.

Mentoring:

Having successfully gone through both undergraduate and postgraduate university applications, I am also happy to help you out with navigating the tricky process of the uni application, from school choice down to the personal statement and interview.

I believe science should be fun and engaging, and I want to make sure you have the best possible experience of it!

How can I check if my reaction equations are correct?

The basic principle about chemical reactions is that whatever goes in one end, will undoubtedly come out the other! The simplest way to make sure your reactions are correct is to count what you have on each side. Your reaction needs to be balanced, meaning that the number of atoms needs to re...

The basic principle about chemical reactions is that whatever goes in one end, will undoubtedly come out the other!

The simplest way to make sure your reactions are correct is to count what you have on each side. Your reaction needs to be balanced, meaning that the number of atoms needs to remain constant throughout. So, for example, if you have eight carbon atoms on one side, make sure you also have eight carbon atoms on the other side as well.

How do internal stimuli affect a positive and a negative feedback loop?

Deviation from homeostasis causes the activation of feedback loops in order to restore equilibrium to the organism.  An example of a negative feedback loop is the homeostasis of blood glucose; the increase in glucose levels stimulate the production of insulin by the pancreas, which in turn ca...

Deviation from homeostasis causes the activation of feedback loops in order to restore equilibrium to the organism. 

An example of a negative feedback loop is the homeostasis of blood glucose; the increase in glucose levels stimulate the production of insulin by the pancreas, which in turn causes the uptake of glucose by tissue cells and the formation of glycogen in the liver. This process is repeated until blood glucose levels return to normal, where there is no excess glucose to stimulate insulin production. 

Contrary, a positive feedback loop causes amplification of its causal stimulus. An example of a positive feedback loop is the propagation of nerve action potential;a small secretion of sodium ions through sodium channels on a nerve fibre causes a change in the membrane potential, which in turns leads to the further opening  of sodium channels and an explosion of sodium ions. When the ammount of internal sodium drops, the membrane action potential reverses and the sodium channels close.

What should I focus on in my personal statement?

Your personal statement is all about conveying why you are a good candidate for what you're applying to, but this doesn't mean you should only be focusing on your academic achievements! Extra-curricular activities, personal hobbies, and even experiences that impressed you are all worth mention...

Your personal statement is all about conveying why you are a good candidate for what you're applying to, but this doesn't mean you should only be focusing on your academic achievements! Extra-curricular activities, personal hobbies, and even experiences that impressed you are all worth mentioning in your attempt to bring the following point across; "I am interested in this, and here's why". 

A well-rounded personal statement is the mark of an open minded individual, and universities tend to seek out students who exhibit not only a passion for their subject of choice, but for learning and challenging themselves in general. 

So while focusing on your academic interests and achievements is definitely essential, it's always a good idea to talk about other things that fascinate you in life, whether it be competing in your favourite sport or trying to make sense of the science behind Star Trek.
