[DT1]Maybe you should use 2000 here. I know you are trying to be accurate, but it kind of gives the impression that you did a 4 year post-doc.

[DT2]Missing a word here? Maybe “structural”?

[DT3]Use for what purpose?

[DT4]You need a note here – this research has resulted in…

[DT5]As above

[DT6]As above.

[DT7]Missing a word here? Maybe “structural”?

[DT8]Use for what purpose?

[DT9]I would estimate the value here rather than describe what you actually got…

[DT10]Too much detail in the part I deleted.

[DT11]Are you required to mention that this was not funded the first time? If so just use resubmission before the date.

[DT12]As above.

[DT13]Looks great that 3 of the 4 courses you taught have chemistry in the title!

[DT14]I would bold, italic for continuity with the invited speaker ones…
