iiwanovic, that makes more sense now.

I wouldn't try to prove equivalence but do analysis of variance (ANOVA). It is where you are comparing how different variables affect the overall result. Ie take all your data with all the variables and analyze them together to get an overall equation. It means you can possibly look at interactions between the variables and thus determine the more important variables. It lets you use your entire data set at the same time and you can compare anything as long as it has the same output (ie yield or conversion).

I don't really understand the underlying theory so not going to try and explain it but I use DesignExpert to do all my multi-variable analysis. There are a few other software options like MiniTab or SPSS that do similar or you can try ANOVA from scratch.

Hope that helps

Hi lucedan,

Thanks that looks good, I will give it a try. Though it is sad that the grant databases are all subscription models when a lot of the money is from charities and government. I don't ask myself as my supervisor is always asking herself.

Literally, at the end of every meeting, my supervisor always says something like "I want to do X but don't have the money, I am applying to Y, do you know anywhere else I can try" to one of the other attendees. Usually, they suggest somewhere. She also regularly asks at the end of an email something like " do you know any new funding opportunities coming up?" Her attitude is to ask people after having a conversation about something else and generally, people are helpful.

I know in my university there are various funding co-ordinators who as part of their job actively look for money and send out weekly emails. Maybe you could find someone similar?

My opinion is that statistics aid an argument but cant compensate for bad experimental design. Understanding the theory first is better than trying to use statistics to determine a conclusion especially with equivalence in what I assume is chemistry/biology.

Do you have 4 sets of experiments measuring the same reaction or different reactions? If you are using four different methods you need to understand how the methods would affect the result (ie are you actually keeping everything the same). If it is different reactions they are different reactions and looking at theory is better than using statistics. It could coincidence that they are the same or they have a similar rate limiting step(or mechanism) but you need the theory first.

More details would be helpful but I would really recommend looking at the underlying theory to see if equivalence is possible or is it just coincidence.

Is this the right place to advertise possible Ph.D. topics without having a host university or funding?

I would also say that a Ph.D. student conducting a clinical trial without expert organization (cough pharma companies) would not be approved by the ethics board of most universities. They gave me a hard time and I am not even working with patients, apparently endangering your own life is an ethics issue even if you have an approved risk assessment.

I honestly don't know of any grants database. It would be nice if there was one though.

If you are trying to find grants asking around in the faculty is a good idea. I know in my department there are regular emails about grant opportunities coming up from various bodies. You can also ask researchers directly as a lot of them may be in sperate fields/institutes/email lists that have open funding. Like I got a training grant from an obscure research network that my supervisor was told about by a friend. A lot of the smaller grant bodies don't advertise that much so asking around to find them can help.

Hi Yandex,

Offers can take a while to go through the bureaucracy, I would give it at least two weeks.

I had about 3 weeks between being confirmed verbally and actually getting an official offer via email. They will have to do a lot of bureaucratic stuff like check eligible for the bursary, check references (if they are), check if you actually achieved the actual grades, put all of the above onto the IT system before having someone review over it all. Each step could also be done by different people also dragging it out, so don't be worried.

If the supervisor wanst you, there is a very good chance you will get it an official offer but some things can't be rushed. Though I don't know University is Salford procedures so there could be more to it.

Hope that helps and congrats on passing that interview!

Quote From tru:
Hi, Bloop,

I agree with rewt that a supervisor with little experience will make mistakes. However, I disagree that one has to put up with these mistakes at the cost of one's PhD quality. Your research fellowship/postdoc application does not distinguish between a fully supported PhD lab and one that was not. It is not necessarily true that a first time supervisor will put in extra effort to get you through. I know at least three students who had the unfortunate experience of becoming student no 1 who was neglected while the supervisor was trying to establish his/her lab. Besides, the supervisor generally will not put their best idea forward for student no 1 because they know they have better chance of success when they have established networks/collaborators, have established a research team with trained technicians, have preliminary data and know the academic system better. In other words, generally PhD student no 2 or 3 gets better quality PhD project. I have seen many examples of this. An inexperienced PhD supervisor may have less knowledge to discuss/troubleshoot problems and their reference letter may not be as highly regarded as an experienced/established one.


Being the first Ph.D. student does mean your supervisor will make mistakes but you can also get far more skills and experience than being the second or third student. I am both my supervisor's first Ph.D. student but also the first student in a new research group. I have had to learn/develop several new techniques which I have already got 2 long external lab visits from. Because there is no real research group I am somehow collaborating with researchers from other countries instead. I don't have all the right lab equipment though I have learned so much amount the understanding methodologies to compensate.

An inexperienced but well-motivated supervisor isn't bad if you take is an opportunity to step up and don't expect to be spoon-fed everything. You just have to work harder for better results.

I think it is always better to give too many citations than leave some out. I would check how many citations this book already has. As if it has quite a few citations just cite is as other people have already reviewed it and thought it noteworthy. If it barely has any citations I would be more skeptical.

Just because you haven't read it doesn't mean that you dont have to acknowledge it. The book still exists and your reviewers might be able to read it and you dont want them asking why haven't you cited it. If your supervisor thinks it is relevant, take that as your verification of it being relevant enough to cite. The worst case scenario is that you get accused of plagiarism of their work and citing it generally stops all that nonsense (I know it is far fetched but that is why cite other people).

Hi Bloop,

Are you married or something? As when you say "divorce" in the title it suggests there is a relationship or do you mean that you want to quit your PhD?

It sounds like your supervisor is inexperienced but that happens. Mine finished her PhD in 2015 and I am first Ph.D. student so I am in a similar position. You got to remember she is just as inexperienced as you but she is actively working at it and learning from mistakes. She will make mistakes but she will also probably put far more effort into getting you across the finish line than other supervisors as you are her first one. She may be super busy but it sounds like she is making time for you, which is a very good plus as a lot of supervisors barely respond. She may lack an eye for detail but maybe ask other PhD students to proofread and vice versa?

About dr Freeloader, we all know those freeloaders/second supervisors that are annoying but what harm are they doing? A third name on a paper isn't that much in the grand scheme of things but I know that it is annoying but you may be able to return the favor one day. Also did you not want a second supervisor or want to chose your own? Because having a second supervisor is always bloody useful and if you chose your own you could always have the dreaded supervisors not agreeing situation. Remember you are a still student.

You complain about the research focus, not 100% aligned with your interests but that is a sad sad part of academia. Unis get money from universities to research particular things and if you want their money stick with it, there is less and less unallocated money these days. If you really want a career in academia you better get used to following the money.

How far into the PhD are you? As it is always easier to quit the earlier through it you are but the grass is not always greener.

I got a mid-low 2:1 (including on dissertation) but got a fully funded PhD. From all accounts, they were impressed with my written application and I nailed the interview. So you can definitely do it with a 2:1.

I think they will read applications from anyone with a 2:1 or above but you need to make yourself stand out to compensate for the low grades or have a very good excuse. Grades are good indication of how much you know/ work ethic so you need to be better than the other applicants in other areas. If you think you can do that go for it or even go for a self-funded one.

Though I was that guy that drank 4-5 nights a week and never turned up, so maybe I am just lucky.

Rewt I love that suggestion! I'm not sure I'd get away with it where I am. I also didn't attend alot when I was an undergrad but I never had the balls to email the lecturer to ask, I used to rely on friends!


Yeah, I never had the balls to email the lecturer if I didn't turn up either.

Is there a book that you could refer them too, instead of answering them individually? Or give them some pre-made notes? Or if they are asking the same questions, tell them to ask the other person who asked/ forward them those emails. The department wants you to be supportive and available but you dont need to give a tailored perfect answer every time. Directing them to the right place may be enough.

Or every time they ask a question, say "is this what you mean ..." and copy/paste the answer from someone else. Half-time they might just drop it but the really dedicated ones will only ask the second time. Could be a good screening process but I have no experience in teaching a full class, so take my ideas with a pinch of salt.

Similar to Tudor_Queen, I have zero relevant experience

Why do you really want to do a PhD? You mention passion and that you want work in areas you are interested in, why do you need a PhD to do that? Couldn't you get a new job or start a few Github projects in your spare time to challenge yourself or do you want the structure/environment of a PhD? I am asking because a PhD project can be fun and challenging but at the end of the day, it is still a huge pile of work with commitments. If you get that challenge or interest going without a PhD, I would do that over the PhD.

A part-time PhD can be easy to drop out of but if you are truly passionate, I have seen a few people do it. Just set clear boundaries and goals, then stick to them, a part-time PhD is a lot of self-discipline but if you think you can do it, go for it. One of the things with a PhD is that you have a lot less direct instruction from your boss (normally) so you have got to have that self-management skills, especially with a kid.

An idea, would it be possible to go part-time at your job, so you have 1-2 days a week to work on the PhD? It might be easier financially than full-time and you will have dedicated time for the PhD

Though if you do go full time, I bet you would finish it on time or even early as you will probably have a better work ethic than most PhD students (and maybe most lecturers).

Just my thoughts, hope it helps.

My thoughts as the student with sub40% attendance during his degree is that if they think they can pass it without turning up, they won't turn up. Most people are at uni to get the piece of paper at the end so the only thing motivating them is the results. As I thought that the module was easy I didn't attend. Didn't matter about teaching style or engagement, if I thought that I could pass with minimal work I stayed at home. If I knew the course was hard or that the lecturer who based exams only on what he said in class, I attended whatever the lecturer's ability to teach.

So literally fail a lot of people one year and the next year you will have good attendance. In my undergrad a lecturer did that because her attendance was allegedly 10% (wouldn't know as I wasn't there), so she made an exam that was barely based on any of the lecture slides. The result was a pre-standardised average of sub 30% and she held her ground so that during standardization most of barely passed. Word spread and the next year she had high attendance because she suddenly had a hard module (it was a core module).

My opinion is that with this drive for "e-learning", recorded lectures and online notes makes lectures far less appealing when you can do it all in the comfort of your bed. So don't take it personally and if you want an easier time without failing people, listen to what they are asking and add it to your distributed powerpoint/notes for next year or make an FAQ site.

Also, is your lecture at an odd time, end of the day or is the only lecture they have on the day? Timetabling may just make your lecture awkward to get to.

Maddy I would take the job.

You can always do a PhD later with a few years of civil service experience to help you as the others have said. I think you should always take follow option that you think that you would regret the most if you didn't take it. Ie you can always take a career break and do a PhD but it is far harder to get a second chance at the civil service fast track.

Quote From Virshininke:
Thank you rewt, that helps a lot. So do you ever have any lectures at all or is it more about just seeing your supervisor?


In the UK we dont have any lectures or coursework as part of our PhD so we have less "supervised" work (though we are usually expected to have a masters before starting which kinda compensates). So as long as I am showing results and work I keep my supervisor and Uni happy. Though I do meet or call my supervisor weekly to catch up on what I am doing/ what I should be doing.

That is the thing with a PhD in the UK at least, you are usually measured by results, not by the number of hours in the office. In theory, I could only come in for labs and do the rest of my work in the middle of the night at home, so I am not physically bound to a desk.

Virshininke, you are considering full-time or part-time based on workloads? Generally, I would say if you can get funding go full time as there is less time management hassle as you only have to manage one thing. Or do you have other priorities to consider? Also what field are considering as certain areas require more/less time in uni?
