The phrase 'challenge for studying' is correct and can be used in written English.
For example, you could use it in a sentence like this: "Studying for this exam is a real challenge."
A major challenge for studying authentic liver cell function and cell replacement therapies is that primary human hepatocytes rapidly lose their advanced function in conventional, 2-dimensional culture platforms.
Molecular dynamics simulation has played an important role in uncovering the fundamental mechanisms of dislocation nucleation, but its limited time scale remains a significant challenge for studying nucleation at experimentally relevant conditions.
The gigantic sizes of MLL2 and MLL3 pose a challenge for studying them.
A challenge for studying the poly A- transcripts is to distinguish the true poly A- transcripts from the degraded transcripts originated from in vivo physiological RNA metabolism or in vitro RNase activities (which also lack the 3' poly A tail).
The lack of a true placebo condition for visible light interventions is the greatest challenge for studying the effects of bright light therapy [ 57, 73, 74].
In summary, the challenge for studying monogenic disorders is to assess the relative contribution of modifier genes to the disease phenotype and to reliably identify these genes, bearing in mind that multiple modifier genes may create a cumulative effect on the phenotypic expression and that the combination of these genes may vary between individuals.
Many pathogens causing disease in humans exhibit nearly unique human tropism, posing additional challenges for studying host-pathogen interaction and for efficiently testing anti-microbial intervention strategies.
One of the biggest challenges for studying gradual change will be the lack of appropriate data for validating results and products.
Challenges for studying this regime include that experimental observations can be more sensitive to coupled physical-chemical processes leading to phenomena such as mixed deflagrative/autoignitive combustion.
However, in the process of applying the artificial bee colony to the VN embedding problem, there are several challenges for studying such problem.
Practical challenges for studying AH under real conditions led us to apply an alternative model to simulate flight-associated alterations in healthy individuals and those who have experienced AH by placing them in a pressure chamber under fully controlled conditions.
